Actually i checked my time slips and there is 285 passes.
I changed the tires from Goodyear eagle standard sidewall and compound i think is m5 to a set of mickey Thompson with l8 compound(softer) and a stiff sidewall.
Went to the track this weekend and with the new tires my 60 foots sucked until i figured tire pressure and had to play with front shocks and back ones............first pass i did a good burn out but had lost .07 in my sixty foots but today i got it to .02 ............the air was better then it has been all year and the car ran .07 faster then it ever has so i think maybe a little more playing and i will get the other .02 back
