Welcome to the fun.

Welcome! Building a Coupe-R for dual use here. Street/track. Post more details of your build plan!

[Flying Tick]

Not many details firmed up yet. Decision to buy the kit was a spur of the moment. I have built and raced motorcycles most of my life but am getting up in years and the bikes are taking their toll.

I have ordered a 427 and a T56 magnum from Roush but that's as far as I've got.

Nice engine pick! And welcome!

What’s the setup like? Standard intake and air cleaner element means hood modification. On the SR model with dual plane intake it’s going to be too high with the R and a single plane intake it’s going to be a gasser. I replaced my filter element with a K&N E3515 which is shorter than their supplied you can spec it before production I didn’t know so I have to pay out of pocket through summit. Also the supplied dual plane RPM performer will also be too high. I recommend the performer intake. I can speak for the IR model but if that’s what you’re going with I’m jealous.

This post might help

I take it you’re doing a solid axel in the back otherwise the FFR driveshaft will need to be shortened further (it’s already very short) if you’re doing IRS with that T56.

Have fun and enjoy and if you need help with you’re setup I’ve been down this road.

[Flying Tick]

Doing a IRS.

Against almost everybody's advise I am going to use either a borla or a Inglese crossram, because I want to and I can. I understand that some hood mods may be required but that's what we do to build a car the way we want it.

I'm also using a crank trigger and DIS, again, against advice, but I want to and I can.

Looking at the front shock mounts and the FF supplied bottom a arm and was wondering if those that have built a track car thought these are strong enough?

Received QA1 coilovers, went with DD404 front and rear, 850 springs up front and 700 in the rear also received front brake setup from Wilwood today, pleasant surprise since I only ordered them on Friday

Front Brakes are
Wilwood FSL6R/ST calipers on 14" Rotors. have to modify the caliper mount bracket to center the caliper.

Hopefully more stuff will arrive tomorrow

I am a dealer for most everyone you listed above Including Borla and Fast. The 404 from QA1 are too long.

[KDubU]

Cross-rams are very cool. Saw one on a Backdraft that was really nice.

[Logan]

I am a dealer for most everyone you listed above Including Borla and Fast. The 404 from QA1 are too long.

A quick google search shows the QA1 DD404 shocks have a 15” eyelet-to-eyelet length. That’s the same as the Koni Reds that come with the Coupe kit.

[Flying Tick]

Thats what I came up with to

Koni 30-1720
11.10
15.15

QA1 DD404
11.125
15.00

[Gordon Levy]

Your right, my bad. I usually use the 401's. I am curious as to way you would order bushings instead of bearing mount.

[Flying Tick]

Gordon, last time I raced cars was in New Zealand in the 70s. So all this is relatively new to me. Knowing that there will be changes along the way I had to start somewhere.

[Gordon Levy]

OK, there are ton of things that we can talk about if you wish. We have built quite a few of these for racing and there are some fitment issues with some of these parts that I can help with, along with some of the reasons behind some of the things that should or shouldn't be done.
