One run at an airfield that us Northern Californians get to run at.

I was not there to get a good lap time but more to thrash/laugh and see how the car behaved - not looking for technique critique.

Tires are Toyo R88R which being a track tire I THINK need to get some real heat into them to grip well.

Still, November in California.

This past week was drags, HPDE and AX - the car was all good.

How do you get that bird's eye view?

I love that camera view Dave!. Nice smooth lap, love how the camera angle shows the areas where the rear was just sliding a bit.

Questions - what shocks are you running and what does "ARB" mean in your signature? I'm assuming swaybar...

Also since I've watched so many of your videos, anything you've broken, worn out, would change or do differently to your car for the performance events? Did you find the rear swaybar make the rear wash out/oversteer too much (which is what they can do)?

Thanks,
Hank

I'm using an Insta360 X2 360-degree camera mounted on a boom off the back hatch.

The camera has two lens that each capture 180 degrees of data which get stitched together into a 'sphere' of data with the camera at the center.

In software, the boom is edited out and the point of view can be set to whatever you like for a final render to a 'flat' file that the one of my autocross run.

It's pretty neat.

Cool stuff that I didn't realize even existed.

Hank- I think that I owe you reply to your build thread as well.

'ARB' yes, anti-roll bar.

My coil-overs are QA1 single adjustable with 700f/500r springs- IRS.

I've never, ever been able to get the car to understeer- not that I want it to - just sayin' from a chassis tuning perspective.

I'd say the big lessons have been cooling- I needed coolers for both power steering and oil.

I'm running a KRC power steering pump now with a tube/fin cooler but before this I cooked a couple of OEM-style pumps even with a cooler.

My oil cooler (engine is a SBF 302) is now horizontal in the radiator outflow duct - like one of the original cars - it works well - you can fit a big plate cooler in there.

Other than that just some worn Heim joints in the rear end.

I'd say the biggest thing to be fast on a road course is brakes- invest in this all you can.

Thanks Dave. Oil cooler for me sounds like a good investment. Going SBF 347. My rear springs are 350# and 650# front but that is assuming use of the rear swaybar stiffening everything up....thankfully very easy to change springs on QA1s (and I assume the Konis). Got to get her built first, then can play!
