What are your 60' times with street tires.

I made 13 runs back to back, and I could not get any lower than 2.301 seconds.

I have Good Year Eagle F1 (wow, what a tire! 80% dry grip in the rain!)

 

If you lower the tire pressure to about 22 psi and work on sliding the clutch, you'll get 2.0-2.1 60's. If you bring that 60' down .2 that will translate to about .3-.4 faster on the other end of the track. With drag racing the only thing that matters is the launch and 60' times because once that is over it's the same old thing....redline, shift...redline, shift.
