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 item fits the following BMWs:
1992-1999 E36 BMW 318i 318is 318ti 323is 325i 325is 328i 328is M3 - not for convertibles

These rubber bushings from Meyle are a direct replacement for the stock differential bushings in the E46 3-series, E83 X3 SAV, and Z4 Roadster. If your original bushings are worn (likely around 100,000 miles) these are a great replacement upgrade. The front bushings are the stock OEM type rubber bushings. The rear bushing is a Meyle HD upgrade over stock - about 15% stiffer than the originals. This means the bushing will not flex and twist as much. This puts more power to the wheels since power is no longer used up for 'torquing' the bushing. These are not race bushings; the rubber material is perfectly suitable for street use.

The non-M E46/E83/Z4 models use three differential mounts - two front bushings in the subframe and one rear mount in the diff cover. This set of bushings covers all three. You can opt to include new mounting hardware in the Options list below.

This item fits the following BMWs:

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 heart of the rear suspension, the subframe (or carrier) mounts located the entire rear suspension to the car. There are four mounts in total and bolt up into the rear floor. Worn subframe mounts are one of the leading contributors to rear floor-subframe failure. As the mounts flex, so does the sheetmetal of the chassis, which will fatigue the sheetmetal and crack the spot welds. Therefore, replacement of the subframe mounts is critical and a must when doing the subframe reinforcement or repair. This kit comprises OEM Lemforder and Meyle HD rubber subframe mounts. Solid aluminum mounts are also available with very little increase in NVH.

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.

The next time you replace the motor mounts, oil pan gasket, checking your oil pump nut, or any other time you drop the front subframe, you should install these reinforcements. This kit comes with steel reinforcing plates that are welded to the underside of the guesset as well as plates to close off the bottom of the gusset for extra strength. Instructions included.

If you already upgraded your suspension but are looking for the finishing touch, this kit is what you need. The BMW front strut mount reinforcement plates reduce the risk of the shock tower mushrooming and cracking. The ECS rear shock mount reinforcement plates reduce the risk of the rear shock mount area tearing and deforming. The ECS Delrin rear trailing arm bushing limiters reduce the movement that the RTAB's can make resulting in a tighter rear suspension and with less moment prolongs the bushing life.
