Millway Motorsport Rear Shock Mount Reinforcement Plates for all E30, E36 and E46 models including M3 and Compact, as well as E36/7 Z3 models and E85/E86 Z4.
These 3mm thick S355 steel plates work perfectly as either a bolt-on or a weld-in reinforcement, adding strength to the rear strut tower for all cars running stiffer shocks or coilovers.
Priced per pair.
