One of the biggest regrets I have is selling my beat-up ass nx hard top. It had only a 10:1, HS WAI, stock lightened FW, act clutch, jwt/es motor mounts, ur 2pc pulley set, suspension, and weight reduction(yes stock header, exhaust, cams, ecu, fuel, etc...) and ran a 13.9@100 on streets w/ only a 2.1 60'. coulda been in the low 13's, maybee high 12's w/ s4's, ecu chip, nice header, exhaust, and slicks. beat-up ass nx on stock wheels flat blacked. sleeper as hell. Beat up on many a 5.0's.
