My car has pretty much always gone straight on the launch and doing burnouts. Now for some reason it wants to go hard left. The suspension is all aftermarket LCA's and spohn torque arm. I removed the single adjustable shocks and installed DA AFCO big gun 3870's. Still doing the same thing. It has a Moser 9 inch and a stock 3rd gen rear sway bar with poly mounts and bushings. Fronts are 90/10's. It's never needed an adjustable sway bar so I don't understand why it would now. Last time out rolling into the throttle it only 1.40 60' and went 5.93@119 mph.

Tonight I drove around for an hour and stomped the pedal rolling at about 30-40 mph and it still did the same thing...hard left. I've checked out everything and nothing is loose or broken that I can tell.

 

Hows the rear alignment?

 

according to the alignment shop it's within spec.

 

check tire pressure recently?

 

Yes, in the staging lanes before every pass.

 

Verify you dont have a stripped or otherwise damaged axleshaft or differential

 

It has a spool and leaves two black marks during the burnout. I'll inspect after work to see what I find.

 

I jacked the car up and verified that the axle isn't broken. I don't think it's stripped because it leaves two marks during burnouts. I'm leaning towards the LCA bushings being worn out.
