went to the track last night. i only got to make one hard run and it didn't go so well. 12psi and a 100shot and i completly blew the tires off, they didn't have a chance. i spun all 4 past the 60' mark.

my tire presure was 34psi, anyone have any luck droping presure on street tires? should i clean them off before a run? should i warm them up? seem like the stock firestones hooked up better but i didn't get enugh runs to say that for sure. do tires hook better after a few miles? btw i am running 285/65/16 perilli scorpions, they do look prety cool.

i did drive to the track, run an 11.5 at full weight (including the gate and pasenger seat). Then drive it home 60miles in the pooring rain. 11.55@117 with a 1.80 60'. weak 60' and i it was missing bad up top.

ok, thanks, now about cleaning them off, warming them up, breaking them in.

 

11.5 isn't bad. Just be glad you didnt have to slam the brakes mid track.

 

I run 285 70 16 yokohamas and they don't hook as good as my stock tires did when they're at 35 psi. I drop the rears to about 23psi and drop the fronts to about 28. This gives them a flatter contact patch.

Try that. Maybe you should go g-tech some 60' with different pressures.

 

 

Hey Parish I find that if you just clean them off mine hook pretty good. not a smoking burnout, but just enough to get them cleaned of the debris in the pits, and staging lanes.

 

Make sure you drive AROUND the water box ... I dunno if you are already doing that, but doing so, and cleaning the dirt off them should help a little.

 

also, the stock firestones i think were 4ply tires.. so they will flex alot and help with your traction. i bet the pirilies are 6 or 8 ply, and are more rigid. therefore they will spin intead of geting a good bite.

 

Why don't you go practice on the street and see what works best?
