QA1 problem

I’d bet money it has nothing to do with the QA1 K member itself and everything to do with the alignment. The K member shouldn’t even effect half the stuff you’re talking about. The alignment, on the other hand, could be responsible for a lot of it.

Sorry, we need to see the alignment specs. Most of what you described sounds like an awful alignment, but without he numbers we’d all just be guessing. And we need to know what else you have for suspension. Control arms, strut rods, torsion bars, brakes, tires, wheels, all of it.

Also, it would be a lot easier to understand you if you use some punctuation and do a little proof reading before you post.
