E36, E46 Rear Shock Tower Mount Reinforcement Kit

A very common weak point on the 3 series BMW is the sheetmetal of the rear shock tower. The sheetmetal here is relatively thin and very susceptible to stress and fatigue. A worn out shock will bottom-out more often and this energy is transferred through the bump stop and into the metal chassis. Stiffer shocks and shock mounts also put more stress on the sheetmetal. Factor in age, mileage, and environmental conditions and it's not a surprise that we see shock tower failures often. BMW addressed this issue with reinforcements of their own but our's are thicker for additional strength. This kit mounts on top of the shock tower and can either be bolted or welded in place. Because of the shape of the rear shock tower, these do not fit cabrio/convertible cars.
