01Overview
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 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.

05Options & Notes
Fitting notes
Hand these to whoever fits it.
01The subframe has to come out of the car, so it is worth doing the rest of the rear axle on the bench in the same session — kit 036048B (or 036140B on an M3) covers the arms.
02Reinforce the subframe mounting points first. Polyurethane passes load straight into the floor instead of absorbing it, and StrongFlex's own advice for rally and drift cars is a strengthening plate or a brace before these go in. It is the standard E46 rear-end fix and worth doing while the axle is already out.
03Grease the bush surfaces on assembly — StrongFlex include the grease for it.
Red or yellow?
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.
