GTR pro street tire record Roebling road 1:12.9

Set a new PBR at Roebling after installing tikt brake ducts and Tikt front and rear aero . Still on 285/335 Cup2 ZPs. This chassis keeps impressing me , outrunning race cars on slicks.

​​​​​​​That's awesome, George! Congrats. Didn't look like brakes were much of a factor for that track/lap. Guessing the aero was critical. You looked very planted and your lines were perfect. Kudos.

Mind sharing your suspension setup? How many clicks from full soft for high/low compression and rebound.
Great lap there

I will just comment on my PRO set up. I am one click away from max on both compression and rebound.
My local track chief instructor used to race AMG GT3s. I let him take may car for a few laps and went with his recommendations.

FWIW, I've been running max on both compression settings and rebound setting. I started with the stock setting and went successively "harder" from there.

I run mostly on short, very twisty tracks and have the wing set to max, as well. Camber is about -2.75 deg front and about -2.57 deg rear.
