I have good ones for sale .I also can check yours and in many cases repair it back to factory specs. I also buy rear trailing arms that are bent to make tubular arms for the e30 guys so they will stop using up all our stock arms for the z3 M. any questions feel free to contact me . z3hardtops@gmail.com Michael I also install the caster and camber kits. if your subframe is bent only slightly these kits will allow for proper alignment. All work on precision jig.
