Went to the track last night and ran my best time 12.7 but messed something up on my car. when i drive slow in 1st or 2nd i get the little hop feeling in the rear like its bouncing or something is bent under it. it stops when i go faster. Any ideas would help a lot thanks michael

 

I would get it on a lift or jack it up. It's too hard to call but you may have snapped a half shaft.

 

found out today that it is a broken spider gear, going to put 4.30 in it now!

 

how much power r u makin in ur cobra to the wheels, stock internals? nice run

 

at least it isn't anything too expensive.

 

with the bottle 411rwhp 317 without, did not run on bottle thursday night, the nos stand was closed there. Just got it to hook good and i ran at jackson in sc. yep stock internals
