FB kit should be bolt in? So I doubt that could get too far off? I'm just guessing. If the alignment guys are decent they should be able to tell you what's off. Had mine done and rear left is close to perfect. the tech said it probably tapped a curb in its life. Maybe you have some tweaked suspension components

 

could be a rear wheelbearing. check how the rears rotate. Mine made no noise, but i did notice a pull off throttle

 

rotation seems fine. Im thinking it could now just be the tires getting greasy. Ive had it aligned and the kingsperformance roll abr on the way, should be here tomorrow.

I get 1-2 good 3-5th gear pulls before the car starts going wild again. Im not logging or else derek could tell me if its wheelspin. Im borring another guys 15" drag setup whom is making roughly the same power as I, and he has no traction issue's. That will be able to tell me if im chasing real gremlins or just overpowering the tires. I dont want to order a 15" setup if its not needed yet.

 

So what the hell happened 3 years later.....
