036107B: Rear beam mounting bush kit

The four bushes that hold the rear subframe to the shell.

80 ShA polyurethane — the red compound. StrongFlex match this grade to the hardness of the original metal-rubber bushes, so the car keeps the ride it left the factory with. What changes is what the bush is made of: polyurethane does not perish, does not tear out, and shrugs off oil, grease, salt and solvents.

This is the mount that takes the whole rear axle's load. When the original rubber softens, the entire subframe rocks under power and the car feels like it has a hinge in the middle of it. Four solid polyurethane bushes tie the axle to the body and the drive goes straight to the wheels.

Every StrongFlex product ships with the correct grease for fitting.

• 2x 031350B Rear subframe – front bush
• 2x 031351B Rear subframe – rear bush

Fits BMW 3 Series E36 (90–99) and the E36 M3.
Replaces BMW parts 33319059300 and 33319059301.

The subframe has to come out of the car to change these, so it is worth doing the rest of the rear axle in the same session — trailing arm and control arm bushes are all right there with the axle on the bench. Kit 036046B covers them.

Red 80 ShA — close to the original bush hardness. Stability and precision without giving up comfort.
Yellow 90 ShA — for sport and lowered suspension. Much stiffer, made for speed and hard driving.

Both compounds have the same resistance to weather, oil, grease, salt, acid and solvent — the difference is hardness alone.
