You launched at 5K with ET Streets and didnt break anything!?!? What do u have done to have it hold together because im pretty sure if I launched at that with my ET drags than my driveshaft would be comin throught the floor boards to say hello
BBK upper and lowers, springs, aluminum driveshaft and 3.55 ford gears, subframe connectors, welded torque boxes, KYB shocks with quad shocks still on there and a fully crapped out diff as you can see by the one wheel burnout action (this has been fixed see writeup).
My 88 leaving at 6000 with 26 x 11.5 ET streets, no wheel spin. Stock Z-T5, 3.73 gears, diff girdle, edelbrock uppers, SSM lowers, aluminum driveshaft, yukon 28 spline axles, torque box battle boxes, sub frame connectors, 8 point mild steel Comp eng. cage., 4 disk trac-lok.
Haven't had anything break at the track so far, knock on wood.
