Car Bounces after 60 ft. What is causing this??

BINGO... that video didn't look right. follow BOB's recommendation and your 60's should come down and that front will come up even more. Then you can start moving that launch RPM up till yours 60s start to fall off.

now lets get into engine specs and rear gear size. What are you shifting at and what RPM is it crossing the 1/4 stripe?
