I run the 305-35-19 Nitto 555r2s and really like them for my power level. My best et with those are 11.18@125 w/1.63 60ft. Just a few simple mods, E85, Speed Engineering long tubes and not cats. My C7 consistently hooks every time and rarely see over a 1.67 60ft. I hope to do some tuning on the tranny and break into the 10s this spring. I may need to find a ported MSD if I can't do it with just tuning. I know my Vette is a couple hundred pounds lighter then the Camaro so that is worth a couple tenths. The 305 I run is bout 1/2" taller then the 285 so I don't see any advantage with a 10 speed of running a shorter tire then stock since the A10 has a lower 1st gear the my A8. Yosh6 is right on the shifting on the RPM and MPH, its critical to have those correct so it shifts on time and doesn't hit the rev limiter.
