036241A: Rear subframe bush kit SPORT

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

90 ShA polyurethane — the yellow SPORT compound. StrongFlex build this grade for tuned and lowered cars: the suspension gets noticeably stiffer, the geometry stops moving under load and the car holds its line when you push it.

This is the mount that takes the whole rear axle's load. When the original rubber softens, the 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.

One kit covers a lot of cars — BMW carried this subframe mounting from the E90 generation all the way into the F30 and F32.

Every StrongFlex product ships with the correct grease for fitting.

Fits 3 Series E90 / E91 / E92 / E93 (04–13) and F30 / F31 / F34 (13–20), 1 Series E81–E88 (04–13) and F20 / F21 (11–19), 2 Series F22 / F23 (13–21), 4 Series F32 / F33 / F36 (13–20) and X1 E84 (09–15) — RWD and xDrive.
Not for the M cars — 1M, M2, M3 and M4 use a different subframe mounting and take kit 036094A.

The subframe has to come out of the car to change these, so it is worth doing the rest of the rear axle on the bench in the same session. Kit 036242A covers the arms on an E90 or 1 Series.
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.
