anyone use stoptech bbk for Z4M? possible group buy?
Anyone have any experience with any of the stoptech BBKs for the Z4M's? I was looking into trying a group buy here. At what price range would everyone be interested? What are you finding them retailing for? I am looking to replace my fronts at least with something better and these seem to be a pretty great deal and have heard a lot of good things about stoptech.
