036048A: Rear suspension bush kit SPORT

The rear axle of an E46, rebuilt in one box.

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.

The rear is where a tired E46 gives itself away. Worn trailing arm and control arm bushes let the toe swing under load, and the car changes its mind halfway through a corner. New polyurethane pins that geometry down, and the back end starts doing what your right foot asks instead of what the rubber allows.

Every StrongFlex product ships with the correct grease for fitting.

Fits BMW 3 Series E46 (98–07) — RWD, Compact and the 4x4 xi / xd — plus Z4 E85 / E86 (02–08) and Z4 E89 (09–16).
Not for the E46 M3 or the Z4 M — those cars run a different rear axle and take kit 036140A.

Choose the quantity you need. On a car that is dropped far enough to change the steering knuckle angle, this bush is not the right part for the upper knuckle mount — in that case take 2 pieces and leave the upper mount alone.
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.
