Your BMW's suspension mounting points are notorious for failing to hold up over time. This type of failure is accelerated and aggrevated on cars that are driven aggressively, tracked or raced. The longer you let your car go without repairing or reinforing these mounts, the closer it gets to crumbling apart. Reinforcing existing chassis parts is just simple preventitive maintenance.

E36 Front Subframe Reinforcement Kit
(more info) As E36s get older and see more track-use, they
start develop cracks and bends in places that see a lot of stress. One of the
most stressful areas is the front subframe. It's a good idea to reinforce your
front subframe the next time you're doing any suspension work. This kit
reinforces the upper and lower tabs of the subframe where the motor mount is
located. Requires welding.
These fit all E36 3 series from 1992 to 1999 and the Z3, M Roadster and Coupe up to 2002.
Part #: TDR3675301
Price: $44.95 (USD)
E36, Z3 Strut Tower Reinforcement Plates (Pair)
(more info) The shock towers on the E36 and Z3 are notoriously weak. Under normal driving conditions with a stock suspension it is unlikely that you will ever have a problem. But with a street or race suspension with firm springs much of the energy from pounding the road is transmitted to the thin sheet metal in the strut tower. This pounding will cause the tower to deform or even crack. Look for 'mushrooming' or deformity around the holes for the three mounting studs at the top of the strut tower. These plates will help disperse the energy and save you from costly repairs in the future. A strut brace also helps to prevent this but these plates are designed to reinforce the strut tower from the bottom.

Rear Sway Bar Lower Link Reinforcement Kit - E30, Z3
(more info) This product reinforces the metal swaybar link mounting point on the rear trailing arm. The sheet metal breaks off the trailing arm due to the constant up and down loads being placed on the trailing arm from the swaybar. Problems increase when larger sway bars are used. This product eliminates the problem by thickening the sheet metal and triangulating the mounting point. A good time to install this kit would be when you are doing any rear suspension work, exhaust, or even if you are just doing a differential fluid change.
This item fits the following BMWs:
1984-1991 E30 BMW 318i 318is 318ic 325e 325es 325i 325ic 325is 325ix M3
1997-2002 Z3 BMW Z3 1.9 Z3 2.3 Z3 2.5i Z3 2.8 Z3 3.0i M Roadster M Coupe
