2004 C5 Z06 Corvette at Auto Club Speedway Roval
lap time of 1:49.82
Mod: 315 Falken 615K+ on z06 OEM rear wheels squared and Wilwood BBK. 
It also has some cooling mods, an integrated radiator / oil cooler and Trackspec hood vents to keep the car cool. 
All mods approved by Oli @f Spec Corvette !!

Issue: sticky clutch (common Vette issue) at T3, T9, and T12. The workaround is to use 3rd gear instead of 2nd. I had to lift the clutch pedal using my toe as I enter those turns. Stock seat is crap, I was moving around a ton in the seat. This will be my next mod for this car.
