Going to assume I destroyed another set of stock rotors... Carbotech XP12s, 245/40-17 RE-71Rs (which held up surprisingly well with 4 hours of track time until I started getting impatient on the throttle and overdriving), full exhaust/tune (91 tune, so it's conservative), GT3 air brake "duct" with trimmed rotor shield.

The brakes are pulsing very badly and towards the end of the second day I honestly could barely feel the difference between ABS and the pulsing. Additionally the brakes feel like I'm rubbing really low grit sandpaper on the rotors with low-medium pedal application.

Front rotor:


Rear rotor:



I had an instructor ride along for a few sessions and he specifically recommended an upgrade to the AP Sprint kit. He also recommended a harness... Harness would be a great idea, it's awfully difficult to stay in the damn seat now, lol.

Also, I had the issue with power steering just flat out going away in a few places on track... Two places it was on the brakes, the other was in the Karussell at Shenandoah Circuit. Pretty much every lap and it was a hell of a fight to keep it from hopping out of the karussell It doesn't feel like anything is binding up or contacting, the Whiteline end links aren't hitting the struts and I kinda doubt they're binding up. Not much else to bind up in the front end

Oh, here's a snap of the right front tire which was the worst offender after overdriving a bit.
