I have a '99 Z3/M Roadster in need of subframe differential mount repair, so I purchased the Randy Forbes reinforcement kit. Now I am looking for an experienced shop, ideally in the Baltimore/north DC metro area, to perform the install. Randy suggested that I check with the local BMWCCA for shop recommendations. There are a number of shop recommendations in the sticky on this forum and Bimmerforums. After reading through the posts, there appear several shops with multiple recommendations. None that I have seen, however, mentions specifically the subframe repair. Has anyone had this repair performed at a local shop, or otherwise know of one that they can recommend? Your comments are appreciated.
