Help:Car pulls left under power and right on coast Not sure what is going on. I just had my LCA brackets re-welded and it still does it. Not as bad but very noticable. Please offer any suggestions. I am going to the track this sat and would like to keep it off the wall.
If you have stock LCAs, I would check your bushings to see if they are worn. It could also be the metal insert inside the rubber bushings that is elongated and allowing the rear to skate from side to side. I had a friend's 02' Z do something similar and we found it to be the LCAs.
Check to make sure that the mounting bolts for both ends of the LCAs are tight tight. They need to be tight enough to pinch the steel liner in the bushing hard enough that it can't move.

BMR tunbulars. Non-adjustable. Thanks for the sugestions. I tried tighenning them more and they are tight. But I do want to place them in the stock wholes and see what that does. If it stops, then I know I need adjustable units.
Check the bushings in the are, stock or not, If they are tubular arms make sure the wels on the ends are ok. When I got my car it had aluminum tubular arms and after a few thousand miles the end of the control arm broke at the weld.
It sounds like play in either front or rear links.
More likely rear from the power dependence
and especially so if you still see it with light
brake pressure, working the throttle (so front
is constantly loaded and back is the only
variable).
A long time driving with loose LCA bolts might
have beat out the holes so there's significant
slop possible. If the bolt itself has a lot of play
in the hole, then the jam force may make it
quiet but isn't going to buck full vehicle
acceleration loads and sit still. Might pull the
LCAs, check bolt slop inside the bushings
(sleeve if necessary) and the mount holes
(maybe weld on a tighter fitting fender
washer or drilled plate to locate more
authoritatively?).

Update: I placed the LCAs in the stock location and the car pulls to the right now when power is applied. Not as much as before but still noticable. The rear appears to stay in the same location so nothing seams loose. The vibration is slightly reduced too. I think I just need some good adjustable suspension components to square the rear. I think it will be ok for the track though.
