FFR's own 818R

[Wayne Presley]

It's a really good day when Dave Smith call you up and asks you to prep their 818 and take it to the Grassroots Motorsports Magazine Ultimate Track Car Challenge. Their R&D department is swamped with the SnapOn coupe build, wind tunnel testing and a few other secret projects. The car arrive with an unpainted body and the major components mounted to a new frame. I pulled the body and took the panels to my painter for the paint and body work. While the painter was working his magic I set out on going through the chassis, putting a race alignment on it, wiring the car, putting on the dyno and tuning it. I am 98% done and will have a test day at the track next week and then off to VIR on My 19 for the UTCC!

They picked the right guy for sure! Best of luck.

[BC Huselton]

So glad this has happened. The 818 deserves this track attention IMO. It looks great. The Goal is to get under 2 min a lap...Correct.

Good testing at Roebling. I will see you at VIR, bringing my car on the trailer, can't get it off! I will check in the end of Apr to find out the schedule and how to get in. Are you staying for the weekend NASA event, or heading home after the Challenge?

Do you have any idea who else is coming from FFR? Dave? Others? Is FFR going to tell everyone what is going on with this?

Good for all of us that you are doing this. Thanks, BC

[Hindsight]

Looks awesome Wayne! Do you happen to have any good pics showing how you did the radiator ducting?

[Mark Dougherty]

Fantastic Wayne
They picked the best.
I cant wait to see it go.
And I will see you there.

[Aero STI]

Looks great!

So, did I inspire the hood venting on this car? :cool:

[Canadian818]

Good stuff! We'd all love some pics of what's under that pretty body, and maybe you're alignment specs.

[Mitch Wright]

Car looks great Wayne and making good power, looking forward to a report.

Would be interested in seeing your baseline set up.

[mac1]

I found myself starring at these few pics for a few minutes, great work Wayne.

[Wayne Presley]

Going to Savannah on Thursday to do a shake down.

[Mitch Wright]

Wayne, is the car running Yokohama's or Hoosier's? Red Koni's or the double adjust Koni's, that is a impressive amount of spring, something else to try.

The car sure looks the part and I like the FMIC too, lots of trick stuff.

[Canadian818]

Thanks for the extra pics and setup info, can't wait to hear how she handles!

Using the 818R red single adjustable Koni's and it has Yokohama slicks. I'm going to run Hoosier at the event.

[Zach34]

When are those side scoops going to be available?

[Hindsight]

Thanks for the ducting pics Wayne. I wouldn't have thought to create a top panel for the duct.... that is a good idea.

[TX-Lou]

Looks beautiful Wayne!

- Lou

[DanielsDM]

Looks great! Who makes the vent panel for the front wheel wells (the one in the front of the doors)?
Also were the rear side vent ducts 3d printed. Kind of looks like it in the pics.

[Wayne Presley]

All of the carbon on the car was hand laid out of a mold. The nose was vacuum bagged and is amazingly light. The headlight covers are the FFR supplied plexi wrapped in carbon vinyl film.

[Mitch Wright]

The more I look at the car the more I like the color scheme, the orange really pops off the silver.

[axelthrasher]

Those aren't the regular FFR 818 canards - are they? They look huge to me.

[Sgt.Gator]

These are the kinds of development changes I've been waiting to see. Good Stuff Wayne!

[Wayne Presley]

FFR's 818R with oils, fluids and no gas 1956 lbs, exactly 60/40 weight R/R distribution. R/L distribution is 50.2/49.8 with me in it.

[Sgt.Gator]

When I look at the roll bar I have to think that a fairing would significantly reduce drag and provide cleaner flow to the wing. Round bars are terribly draggy. I'd love to see a top speed comparison on the same day without and with a fairing.

Are you keeping the power steering powered up? If so , thoughts on how it drives?

[Mitch Wright]

Feed back on the feel with Power Steering will be interesting. I don't find the car hard to steer and has good road feel with the depowered rack with the BFG R1S race tires I am running. I believe Wayne has driven the FFR car without PS so he will have a good comparison.

[RetroRacing]

looks great, can't wait to see the test results on the spring rate choices, running exactly what we are.

I had someone who is very familiar with aerodynamics mention the same thing when looking at the 818 recently. I had a mention of this in my build thread. I'm definitely doing this to smooth out the air going to my wing, even on my S.

This pretty sums up the reason:

Sorry for the threadjack Wayne! It would be great if you and Dave could do a little aero testing on this though.

Damn this this is FAST!!

[flynntuna]

:D:cool:;)

[Sgt.Gator]

Great pics and short but sweet report! ;)

You must have 20' ramps to get it on /off the trailer!

[Carlsonmj]

Holy Moly! I only hope that my 818c build will look & perform half as good as this!!!

Nice job...indeed!

[Wayne Presley]

Done testing ran a 1:16.7 at Roebling and the car ran perfectly. Nice balance, hot tire pressure of 27, water temp of 194, needs .25-.40 more camber in the left rear stupid fast down the front straight.

[Hindsight]

Awesome!!! Did you use tire temp gauges or something? Was there much lag with that front-mount A2A intercooler?

[Canadian818]

Is there a sway bar on this car?

[Mitch Wright]

About 115 hp more than my R I bet it is fast.

[FFRSpec72]

About 115 hp more than my R I bet it is fast.

About 95 more than I have also.

[johngeorge]

Great job Wayne!! Can't wait to see it at VIR in person

[Wayne Presley]

Awesome!!! Did you use tire temp gauges or something? Was there much lag with that front-mount A2A intercooler?
I kept the motor above 4000 rpm so the lag wasn't really noticeable. The A2A intercooler worked decent but the manifold air temps still would reach 149° F at the end of the straight on an 82° F


Is there a sway bar on this car?

No sway bar, the spring rates have the body roll under control.


About 115 hp more than my R I bet it is fast. I was going 154 mph at the end of the straight and was still accelerating.


Great job Wayne!! Can't wait to see it at VIR in person

It really looks great

Overall driving impression is car is just a touch loose in slower corners and neutral to just a touch tight in the high speed stuff. You come onto the front straight at about 104 mph and I peaked at 154 mph. It pulled 1.6 G right and 1.5 G left. I pulled the short windscreen and got rid of the buffeting. I need to add .25° of negative camber in the left rear for clockwise tracks.


About 95 more than I have also. It really accelerates out of the corners very well

Oil temp peaked at 270° F

[FFR-ADV]

Sweet!

[Sgt.Gator]

Sounds great. I wish my brakes were that quiet.

What caused the wobble at 4:23 that sent the right tire into the sand and the spin? Was it too much power at the corner exit?

too much right foot on corner exit and when it came back off boost it spun. The car needed slightly different throttle reduction and less counter steer. The 3 year old slicks really didn't help me out either. I learned the car really lazy spins, I had the track to myself so wasn't concerned with having to really trying to catch it. It was my 7 lap in the car since building it.

Well- I would say that is not good. I would not feel confident in that temp, especially after my experience and the new owners experience.

Nope too much, getting an oil cooler before the next test

Oil needs to be 230-250°F

[ben1272]

Boy, to escape that crash with a broken arm and bruised lung......on his first race too. Makes you realize how very badly things can go.

[FrankRizzo]

Any idea what it would cost to duplicate this build for myself?

[metros]

Do they have the front IC ducted to force air through it?

Are you planning on adding the oil cooler to the front or off one of the side scoops?

Love the nose video!

Love the nose video!

It's a front mount air to air intercooler fully ducted in front of the radiator. Water temp stayed at 192° F for the run. An oil cooler is going to be fed by the side scoop on the drivers side

[frankc5r]

Man, it goes from 100 to 155 really fast!! I noticed you were be easy on the high speed shifts.
Really enjoyed the video.

were you able to simulate those IC temps on the dyno so you could figure out safe timing at those boost and temp levels..

On the dyno, the power pulls were shorter duration. I have the ECU set up to pull timing as the intake air temp goes up.

[Sgt.Gator]

Very cool videos Wayne, great job editing and data overlay.

It looks like FFR or you took a cue from the Gen 3 Type 65 Coupe with the extra roll cage bar diagonally from the center across the passenger area. I wonder if that will become standard like on the Gen 3?

And it looks like the engine cover wants to take flight!

[Vette1972]

Very Nice! Wow what a fast car. The speed picks up quickly. I am not familiar with the car. What engine and transmission are you using?

Great video Tks

[Hindsight]

Oil needs to be 230-250°F

Ok that is what I thought. I'm seeing 250 on the track in 70 degree weather and it will be higher as the weather gets hotter. I have a big O2A oil cooler and have removed the factory O2W oil cooler/warmer, but the cooler is placed in the back next to the transmission where it doesn't get a ton of flow. I do have a SPAL fan hooked to it but it doesn't seem to be enough. I need to put it behind the side scoop with some really air-tight ducting. I also have high coolant temps though and am wondering if better radiator ducting may help reduce the oil temps somewhat as well. You mentioned you are planning on putting an oil cooler in the front; that is a lot of extra hose and oil volume but I wonder if it's the only way that will work.

[FrankRizzo]

Build one just like this for you turn key with the same HP?

Well, the more I look at it, there are some things that would have to be different. I need headlights (to get it road legal so that I can drive it to the track). And I would want a passenger seat. Since I'm new to the car, I probably wouldn't want as much HP off the bat, but would like the ability to get it there. Is this making ANY sense?

Thanks

[RetroRacing]

very cool. Was the shifter giving you problems? I too noticed the rear cowl and weird door extension fiberglass piece want to leave the car at speed.
Our oil temps match water at 185-190 max, but we are running an oil cooler (big one) under our top scoop. AIT's are 125 at the end of the straight with our a2a intercooler on top of the engine, but we are still running the stock VF28.
In terms of safety (arm restraints you bad boy) and maybe look at padding the edge of that fuel cell to save your right elbow when your fighting off the bees in the cockpit!

Great video, can't wait to get ours back on track.

[Wayne Presley]

looks great, can't wait to see the test results on the spring rate choices, running exactly what we are.

I just noticed I had not answered this. The springs work great. With lighter front springs it would drag the splitter under braking at speed. I have not driven the car on a bumpy track so I can't tell you how it works there. THe car is really hooked up mid corner.

[Wayne Presley]

Well I had a little bit of time today so I swapped the stock exhaust manifolds and crossover for a Borla unequal length header I had sitting around at the shop. I did a few pulls and had t add a little fuel because of the increase in efficiency. Then took off the plate style of downpipe and made a new one with bellmouth. Overall it picked up 9 peak RWHP and 36 RWTQ. The average HP was up 36 and average TQ was up 31 from 4000-7250 RPM. It spooled up nearly 400 rpm sooner too, I call that a win

It's on a Friday...

[Mitch Wright]

We just moved and haven't even started setting up my shop. My stuff is split between a container here at the track and trailer which is making it tough to get much done on my ride.
If I get an amazing amount done between now and the 19th I just might have to make the drive.

[Vette1972]

Hi Wayne,

I'm not to far from VIR. What is the date? I can get a Friday off pretty easy>

Len

[Wayne Presley]

May 19th with a FFR car corral on Saturday the 20th

[Vette1972]

Wayne,

I'll to get off and slide down the VIR. It would be fun to catch some grassroots racing. If it looks like I can get there, I'll try to look you up. Maybe you could use an extra gofer. :rolleyes: Thanks for the info. Best of luck!

Well test day 2 is in the books. Added an oil cooler, reducted the intercooler, and put on a fresh set of hoosier A7 and test ended up pretty well. Man the A7's hook up over the old Yokohamas...

That looks like a lot of fun, you were moving!
What does that car have for a muffler? What is the sound limit at RRR?

Wayne,
Car look and runs fast. Great job building and driving.
Is the FP gauge on the left of the screen Fuel Pressure? Why is it bouncing between 30 and 70?

[DanielsDM]

Thanks Wayne. Looks like I will have to put some sort of muffler on mine. Thought maybe the turbo would muffle it enough to keep it under 103db, guess not.

[Wayne Presley]

Wayne,

Because the fuel pressure is referenced to manifold pressure


Thanks Wayne. Looks like I will have to put some sort of muffler on mine. Thought maybe the turbo would muffle it enough to keep it under 103db, guess not.

I was 108 dB one pass but the mic was not 50 ft from the track either.

The FPR maintains the same pressure differential across injector so the ratio of pulse width vs fuel flow remains constant. So when the manifold pressure goes down so does the fuel pressure. Conversly when the motor is making 22 psi of boost the fuel pressure goes up to 65 psi.

I was 102db here at NCM before I installed a small racing muffler with my JDM twin scroll set up, I am now 97ish on a 3rd gear pull around 6900.
I gotta make a new exhaust for this car anyway so a small muffler it's going to get

Was the oil getting a bit hot at the end? It seemed to climb steadily.

Great video btw, it's fun to watch it pass everything on the track.

[Wayne Presley]

I would have been passing more but it was pass by point by only.

[Grintch]

I hope you don't run into the FFR curse that has hampered all the other 818 attempts at the GRM UTCC.

[Maximus]

I can't get there until Saturday, but SUPER excited to visit with the fam. Good luck Friday!

[Martin]

That looks like the other cars were in reverse.

Looking forward to seeing this at VIR.

Wayne: Can you remind me again where you ended up with oil cooling? After my cam shaft seizure, and the fact that I couldn't get my oil above 190F on a 104F day, I am thinking of going with only the back Setrab cooler with a fan and vents ported to the side scoops. I am going to be somewhere around 325-350 HP. Dry sump and minimum of 5 quarts in the reservoir. Chad installed front coolers, and I am planning on leaving them in, but plumbing around them for now. BTW. Your car was awesome on the track. I admire your skill. Rob

[C.Plavan]

I pulled off/let off when the oil got to 240. I see 260+ on the new video when you really push it after a short time. Do you plan on doing more to cool it? Once I went to the different oil pump, it fixed my oil temp issue. I should have done that first instead of adding 3 coolers....

Rob- The rear one should be fine now, if not just connect one at a time. You should not need to make any oil lines if I remember correctly. I did them in a series, so I think I just added on with adapters.

[bbjones121]

I have been away for a little while and now I read this thread after seeing the latest FFR update email. This is awesome! I am so glad to see FFR getting back to the races. It will be great to see what the car can do!

Chad, which oil pump did you switch to? I wonder why it helped the cooling? Maybe by increasing the amount of flow?

[Wayne Presley]

He went down on oil pump size to reduce the heating from over pumping

[Hindsight]

Ahhhh, I'm starting to recall a bit..... when he went down, he didn't go down FROM stock, he went back TO stock right? IE stock is 10mm, he originally had an 11mm on it, then went back to 10mm?

[Wayne Presley]

I think it had a 12 in it to start with and then he went back to the 10mm

[Hindsight]

Got it ok thanks. Good to know, for when and if I upgrade my engine.

[DMC7492]

Looking good on the track!
Curious on the make and weight of oil your running in the engine?
Hate to cause a heated debate, as everybody is running the best oil right?

[Mitch Wright]

I am using Mobil 1 Racing 0-50 in my R.

[Wayne Presley]

I'm using 20w-50 Royal Purple XPR

[C.Plavan]

Ahhhh, I'm starting to recall a bit..... when he went down, he didn't go down FROM stock, he went back TO stock right? IE stock is 10mm, he originally had an 11mm on it, then went back to 10mm?

I'm 95% confident I went from 11mm to 10mm. I'll have to check my old thread.

EDIT: Yes went from 11mm to 10mm.

"I want to think it was the 10cm oil pump. I think the 11cm oil pump was bypassing so much oil because of its higher flow volume. The oil was bypassing all the time with the 11cm, just spinning in the block heating up. I also read the 11cm is for journal bearing turbos- I have a ball bearing- that maybe part of it with the oil restrictor for the ball bearing turbo you put on????)

I also do not think you should not have a closed vacuum block with the Element Dry Sump. The vacuum is working against the scavenge, I know Gator has his working though, but both ARE and Element told me to vent it like I have.

I ran without the flat bottom aluminum piece under the engine. That could of helped cool everything also. I did not notice any handling issues running without it. I may suggest the new owner throw it on and try it."

[Rob T]

I ran every single run with the aluminum piece under the engine. No oil heating problems whatsoever. As I've said, my issue is actually oil not coming up to temperature. Going with only the single cooler in the back (ducted and with a fan) when my engine goes back together. I am keeping the front coolers installed, but not plumbed, just in case.....

[metros]

Bumping this up for a big weekend for FFR. Good luck!

[Plebeian]

Keeping my fingers crossed you can get a clean fast run in without mechanical issues.

[C.Plavan]

Hmmm. Finger-crossed the Curse is lifted, but unfortunately on paper it looks like some darn issues maybe arrose... Grrrrrrrrr.

Wayne Presley nailed it! 1:59.9 in the last race!

What a professional. Each go out he ran faster:

Practice - 2:11.005
Race 1 - 2:05.224
Race 2: 2:02.528
Race 3: 1:59.900

Very hot conditions made tires greasy. Wayne feels the car has more in her!

[Wayne Presley]

The day went well and the car hauled A$$, topping 157 mph on the straights. I had a good day in the car that started with a hiccup with the ball on the bottom of the shifter breaking off just as I was taking the green flag in the warm up session. We pulled a part off the the Koni 818C and got the car ready for the next session. John George's car, Trevor's and the 818R all had Rackpak data systems on them so we were able to overlay the data. We figured out that I was losing most of my time against John in the high speed esses and up to the Oak Tree corner. I put that data to use in the last session and layed down the 1:59 lap time on the first lap before the tires got greasy. I did a cool down lap and gave it another shot but missed an upshift in the esses and had to abort that lap. Not enough time to cool the tires before the session was over so I pulled in. Really great time and could not have done it with the assistance of John George, Jim Schenk, and Mark Dougherty today. I'm tired and happy and off to bed. Will upload videos in a day or so

[Hindsight]

How do you like the brakes Wayne? It seemed like the area the Viper was making (instead of losing) ground on you was in the braking zones, but it's hard to tell from the video.

[DanielsDM]

It looks like tire smoke in the braking zones? Maybe too much rear bias?

[Wayne Presley]

That was the out lap and not warm tires, he just wanted to press it harder on cold tires than I did.

The smoke was tire rub, the brakes were awsome. Pulled 2 G's under braking.

[GUNS]

Wow, that was fast! I can't believe the speeds you were carrying through the uphill esses. Nice job!

225/40/17 and 255/35/18 Hoosier A7's on 17x9 and 18x9.5" wheels

great job out there this weekend.
You really picked it up quick.
great car prep also.
You did an amazing job. and I had a blast hanging with you.
cant wait for the next time.

225/40/17 and 255/35/18 Hoosier A7's on 17x9 and 18x9.5" wheels

Wayne, were you getting tire rub in the front, rear or both? And where do they rub?

[Wayne Presley]

Just in the front and the outer lip. Rubbing only under max braking or hitting the curbs.

[C.Plavan]

How was the oil temp? Nice driving!

[Mitch Wright]

I recall when testing Wayne said he saw 260-270 when really pushing the car, which isn't surprising IMO with the power/boost the car is putting out and running the car to 7500+. I don't recall what FFR has on that car for an oil cooler but would think with the short qualifying type runs the temps wouldn't be too bad. My car with 100+ less hp and the OEM cooler/heater on a 90+ day I will see 225-230 after a 30 minute session. Horse power is heat.

[Hobby Racer]

Just in the front and the outer lip. Rubbing only under max braking or hitting the curbs.

Last question about the wheel tire package, I promise. What offsets are you running in the front and rear?

[Scrmblr2]

That's the kind of video that gets me motivated to build one of these cars. Just picked up a donor car. Now I'm working on funding for a kit. Maybe I missed it, but I assume since the car has a 6 speed in it, it has a limited slip diff? Out of curiosity, what year car is the transmission out of?

When are those side scoops going to be available?

This.

[Wayne Presley]

They're available now in fiberglass, just call Factory Five

[07FIREBLADE]

Wayne since you ran power steering in this car, what were your alignment specs? What would you run if it was at S height instead of the R height. I've got the R springs and shocks on my C right now.

[Mulry]

Thanks Wayne. Just ordered them. I'm guessing the ones on that car are CF? They look sharp but the interior fiberglass ones should suffice for our needs.

[taco20]

I ordered them online, so I didn't talk to anybody. Price was like $168 and change, shipped.

Hey what part number did you order because the ones I found on the FFR parts page are not the ones on the 818R car? I found part number #81145.

[07FIREBLADE]

I was about to ask the same question.

[FFRSpec72]

I'm running the #81145 internal scoops for about a year now, only issue is that they require a 4" hose and most of the brake hose out there is 3" so you need an adaptor

[frankc5r]

What are you using them for?? fresh engine air or brake air or ??
Thanks

[FFRSpec72]

I feed them into my intercooler through the 3" brake tubes and have the intercooler boxed so that the air is pushed through the IC

I went to Savannah to test out the larger radiator and air to water intercooler. I added 2 smaller heat exchangers on each side of the grill opening in addition to my standard heat exchanger. Coolant temps reached a max of 196 after 6 hard laps. The intake temps maxed out at 160 and 125 with the water/meth injection. Now that's when things didn't go so well. The header wrap had rubbed on the belly pan and some of it came off. The excess heat caused the timing cover to sag until it came in contact with the header and it ignited. It burned the timing belt, alternator belt timing covers and PS feed hose. So my solution is to use the DEI gold foil heat sheets on the timing covers, ceramic coat the header, wrap the headers with the DEI Ti wrap, put the form able sheet heat shield over the wrap.

Holy Cow! Obviously the engine wasn't running when the timing belt burned up. You're lucky you're not rebuilding a trashed engine.
Crazy!

Wayne,
My solution was similar.
I bought these 2 product from McMaster.

https://www.mcmaster.com/#93315k51/=18396ic
https://www.mcmaster.com/#3254k91/=1839aty

I was going to wrap my headers and all exhaust with this. But I never implemented it.

Right now I am running with the factory header shields.

A few laps from last weekend

https://youtu.be/GRZb30HRsy8

https://youtu.be/GRZb30HRsy8

[BC Huselton]

Looks like you are hooked up on the Roebling Race line. Some odd turns there especially the off camber one. The acceleration up the front straight seems crazy! Are you on the same VIR tires? Is one of the goals FFR has with this to document your setup and determine if it is transferable to others who trying to make things work on the track?

You are making it look easy!

[UnhipPopano]

Not sure why nobody asked this question. The photo attached shows the gas filler on the passenger side. What was done? Any chance of this being a future option? If this becomes an option, what would the new fuel tank look like?

[07FIREBLADE]

Fuel cell on the passenger side is the reason I believe.

[flynntuna]

I asked that same question a while back. Wayne said because the fuel tank was in the passenger area.

[Wayne Presley]

The fuel cell is where the passenger seat would be so the filler got moved to the right side.

[07FIREBLADE]

What are the alignment specs for this car Wayne sense it's running a power steering setup?

[frankc5r]

Man that is exiting to watch. you scare some drivers right off the track!

Same guy spun twice...second time it just broke loose in the rear and off track

[AZPete]

Wayne, you wrote, "The header wrap had rubbed on the belly pan and some of it came off. The excess heat caused . . . "
Since I don't think this happens a lot on OE Subaru cars, what's different? A lot of turbo Subaru cars have header wrap, I think. Do the turbo OE cars have a belly pan?
Obviously, you are pounding it hard, but is there any other cause for the excess heat and damage? And, how can others avoid it?

No subaru cars have a belly pan sealed up and so close to the exhaust, the stock manifolds have heat shields on them, this is a Borla header and comes closer to the timing cover. How to avoid it, see post 185 above

[AZPete]

Thanks, Wayne. I've been planning a belly pan under my engine, so now I'll re-think it. I have a wrapped Perrin EL header and my street machine certainly has much less boost, stress, speeds and a less-skilled driver than your 818R. But, a heat shield will be a good project for me.

BTW, I'm really enjoying your successes with the FFR 818R! Thanks.

[Jim Haar]

Pete , does your header hang down below the frame ?

It's how close the Borla header is to the timing cover. The Perrrin EL isn't as close and near as much of the cover


Pete , does your header hang down below the frame ?
The Perrin does not hang below the frame

[biknman]

Sorry if this was already noted on the areo package but can I ask:
1. How wide from end plate to end plate is the APR GT1000 wing? I believe they come up to 71” wide. And what AOA is used?
2. Fronted splitter which one? I assume it’s the FFR race. For the front splitter how much lip stick (distance from bumper edge to leading edge of splitter) out are you useing? And the verse how much from the front bumper to the rear of splitter? Also assuming the least amount of ducting in the front is being used ie duct above splitter blocked off?
3. The rear quarter panel duct or vent frame or whatever you call it are those avsilable or where these one offs?

Thanks and keep up the good work!
Dave

[Wayne Presley]

I'm driving currently but will reply fully when I get home

[Wayne Presley]

1: 67" and 0° AOA
2: FFR race splitter extended 4.5" and am using the entire opening from the splitter to hood opening.
3: They are available from FFR, call and talk to Jim.

You're welcome. I'm running 500 front and 750 rear springs with no front sway bar and it is well balanced.

They are up to 32 cars with a max of 50.
