I am not into slipping the clutch too much, but man the best i ever managed with street tires was a 2.0 60ft and a 13.7 N/A from there the only mod i made was MT ET's Streets and cut her down to a 13.1 with a 1.78 60ft.Thanks Ian. It had more in it too. I only got 2 runs that day, so I had no practice. I was slipping the clutch out at 2900ish with zero tire spin, 1.8 60'. I think I coulda got more agressive and made a 13 flat. We'll see this summer.
