[NorthGeorgia]

I have run sport cup 2 (315) on the front with g3rs (325) on the rear. Got 6 days on the cups versus typical 4 on g3r. Cups were crisp on turn in but gave way to mid corner understeer vs g3r (305) on front. Understeer on cups progressively more as outer 1/2 went bare on day 6 but still good consistent pace. Temps and pressure behaved similar to g3r. What i would expect for180 headwear vs 80. Am now running Nankang AR1 (305) on front withG3r rear. ar1s on day 3&4 at Road Atlanta this weekend....
