Baer and Aerospace Components both make rear brakes to support a 15" wheel. I know the Aerospace Component brakes only allow a 15"x9" wheel (start getting into suspension components). I think the Baer is similar.Where can you find this brake kit? I've been looking for anything on being able to run 15in rear wheels but havent found much that doesnt need more work done besides just the instal of the kit.
