1/4 times ?
I have been to the track 4 times this year posting a best time of 13.4@102. My bolts on are o/r X, 2.5'' cat back, cai, sct tune, 4.10s on 245 nittos. Is this a decent time for the mods? and i just bought a new set of 27x10.5x15 MT ET street slicks. How much will these benefit me? Its a 5 speed
