i previous had a 10bolt with 4.10s and stock sway bar/torque arm on it. well ever time i went to the track i could cut 1.8 60ft's on shitty street tires. well i blew my 10bolt up and went with a Moser 9in with 4.11s i order the new sway bar brackets to use my stock sway bar, but they weren't the right ones so i ended up running at the track with just the stock torque arm and now sway bar, when i went to pre stage the car had massive wheel hop so i just let out of it, when i went up to run i reved it to 2900 and dumped the clutch and the rear just hated me it like hoped and almost killed the car. does anyone have any idea what i could be...the sway bar maybe?

 

I would put the sway bar on for sure.
