John, figure each 60 foot tenth equals 1.5 tenths on the top end - so if you can get them to sub 2.0, you're under 12.5 now.

I agree with you on C5 wheel hop. Having run a couple C4s over the last few years, and over 500 miles of seat time in a C5, the C5 has a much greater propensity to bounce the rear wheels than the C4.Mr. Bardahl Haven't gotten any Z06 time yet to see if it's the same.
