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.

This is a NEW replacement polyurethane bushing used in our E46 M3 Front Street Camber Plates. This is a custom-manufactured part for Turner Motorsport, made with our own specifications. Replacement is straight-forward but does require the camber plates to be removed from the car. Price is for each bushing.
This item fits the following BMWs:
2001-2006 E46 BMW M3 with Front Turner Street Camber Plate

The BMW E46 3-Series chassis is one of the most rigid and well built BMW chassis to date. Even so, it still has some of the traditional BMW weak points. One of these is the rear sway bar / swaybar mounts. From chassis to chassis the problem has not been identical, but all the damage we have seen has been related to metal fatigue. The metal fatigue is due to the constant twisting and side loading of the sway bar. These forces on the sway bar will cause the mounting points to fail over time. The failure can happen faster with sway bar bind due to improper maintenance of the bushings. However, proper sway bar bushing maintenance does not totally eliminate the problem. In the case of the E46 the sheet metal for the bushing bracket does not have enough material to support the loads being transferred to the subframe. We have designed the reinforcement to strengthen and redirect the load to stronger sheet metal. Requires Welding. Does not fit M3.

The motor mount area on a subframe is one of those easily-forgotton areas that may be hiding a serious problem. The subframe on the E46 has a gusset ('ear') welded on for the motor mounts. These gussets take the stress of the motor mount as the engine torques (more upgrades = more torque = more stress). Worn motor mounts only transfer more stress to the subframe. Unfortunately, the sheetmetal will fatigue over time even though the gusset is reinforced from the factory. Check for cracks along the welds and an uneven plane from the subframe to the gusset. A total failure of the guesset will shift your engine to the side and forward, taking out many other components along the way and leading to a very costly repair.
