Our GT350 at Buttonwillow. Basically stock except these mods: R replica wing, OEM R splitter, R sized P6GR wheels, 305/325 Eagle F1 R3 tires (OEM ZL1 1LE), crash bolts.. oh and the most important mod, Sonny driving it.
Buttonwillow 13CW last weekend with Speed Ventures. 100% stock, unmodified. Racing the the turbo Supermiata in S1 so I only did one session in the GT350. Finally got a clean lap without traffic then bobbled the last turn. Drat! Tires were a bit too hot by then. Checkered flag out so that was it...
