we put some KB dd sfc's and jet hot longtubes on my friends 02 ls1, and now the car pulls to the left (very noticeably) and the steering was normal before we done the mods, is there anyway we could have messed up something?

we jacked the front of the car under the k-member.

i cant think of anything that would have caused the car to be out of alignment.

i guess get it lined up and see what happens.
any suggestion?

you didn't have the car jacked up for the subframe install did you???

the car has to be sitting on it's fully loaded suspension...otherwise you weld the subframes on and the car could be twisted...basically perminently welding a twist in the frame.

other than that i doon't know

 

That's what I thought of too. Although I didn't load the suspension (I had it up on a lift under the body) it worked out for me. If you just jacked up the k-member and welded 'em that could very well be the problem.

 

we bolted the dd up and they drove to shop and had them welded in with on DRIVE ON lift.....

Did you mess with the steering linkage at all on the Header install? You couldve messed that up somehow, maybe?

 

Align it and see what happens.
