CA: Chassis, Suspension & Steering Upgrades

Product Code: ture36frosubframkit

Click to Enlarge

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)*

E36 cars that see a lot of track-use will develop cracks where the swaybar bushing mounts to the subframe. By welding in this reinforcement you can prevent the mount from failing. Requires welding. This will go a long way towards preventing a bothersome repair down the road.

This rear anti roll bar reinforcement kit can be used on:

1992-1995 E36 318i, 318is, 318ic, 325i, 325is, 325ic
1996-1998 E36 318i, 318is, 318ic, 328i, 328is, 328ic, 323is, 323ic
1999-1999 E36 323is, 323ic, 328is, 328ic
1995-1999 E36 M3 coupe / sedan / convertible (3.0 and 3.2 litre models)

These are the BMW factory chassis reinforcement plates that came on the E36 M3s (some very early 1994-production M3 models may not have had them). This reinforcement should be done on all non-M E36 models especially when used in track/autocross situations. The kit is a set of 4 plates that are added to reinforce the rear subframe chassis mounts. BMW discovered that over time, due to the bending of the rear of the chassis in conjunction with the movement allowed by the rubber bushings in the rear, the chassis mounting points for the subframe would flex, weaken, and if left unattended, rip out of the chassis. The stock mounts are basically a flat plate with an internally threaded tube that are welded to the chassis. The flex of the rear subframe causes the threaded tube and mounting bolt to act as a lever arm at the point where the flat plate is welded to the chassis, weakening the surrounding sheet metal. Due to the direction of force of the torque applied by the drivetrain on the subframe, the first mount to rip out is the passenger’s side front mount, followed by the drivers side rear mount. Having these plates welded to the underside of the chassis significantly stiffens the mounts and stops the weakening of them.

In order to weld these plates in, the rear suspension, rear subframe, exhaust, and driveshaft must be removed. It is also strongly recommended that the back seat, rear interior, trunk interior, and fuel tank are removed and all fuel lines are capped to reduce the fire hazard while welding.

Applications:
1992-1999 E36 3-series - 318, 323, 325, 328
1994-6/1994 E36 M3, (although there is no clear factory transition to building cars with the reinforcement)
