Genericly speaking, yes a tire with a flexable side wall hurts your trap speeds. And usually by a decent speed too. Something like 2-4mph from what I've been able to observe.

All my times were run the same day but the 12.89 on F1s were on my 8th run of the day. So I had a decent amount of runs to practice w/all the new mods. AND I was able to put some 100 octane in starting with that run as well.

So... I think the next time (assuming same weather and same slippery track) I could get 12.9s on the F1s and a 12.6 on the 26.5" ET streets. (cheater slicks)

I really do wanna think I could bust a 12.4-12.5 if I could launch at anything above 800rpms w/out spinning.

69stangsjc, Thanks man!

I never ran her stock. But I would guess 13.5 maybe.
