You can use stock a-arms and stock style coil springs with the QA1. If it has spring perches up top then a tub style k member can run them. I think PA racing, QA1, and steeda are the ones that come to mind.
Is the car sitting to low? You do have the springs in the car? I know over on modulardepot automaticweapon ran the QA1 and he had to do some spring swapping to get it right.
Here is a pic of the spring perch up top
Here is a pic of the spring in the a-arm and in the perch.
according to QA1 the proper fix is to run a shorter control arm. They said to install a coil over set up to fix it the way it was meant to be. Then they said if you run a foxbody control arm with a 96-04 ball joint that will work also.
