Gears, I wouldn't go less then 4.30.
O/R X pipe and some Magnaflow mufflers.
My car has 4.56's and an O/R H and Magnaflows, it's gone 12.9 @ 108 with a shitty 1.94 60'.
Jake, when I was still stock I was killing Cobra's in the 1/8th. After that they frieght trained me on the top end, but it was fun while it lasted.
