My son and I are redoing the suspension on our r56 cooper S, and are thinking about the Bilstein B12 pro kit with eabachs or the Bilstein B14 coilovers and run them at about 30mm - would replace top mounts, bump stops and polyurethane bushings for the steering arms.... What am I getting into? Do I need camber plates on the fronts and adjustable control arms in the rear? Chat thinks I may not as 30mm is pretty modest...
