Powerflex PFR5-4617 Rear Upper Control/Camber/Top Arm Inner Bush Kit (Pair) for BMW E46 3 Series incl Touring/Estate - Polyurethane Wishbone Bushings - Replaces 33321092247

BMW E46 3 Series Rear Upper Wishbone Inner Bush Set, Powerflex PFR5-4617

Give your E46 a proper chassis refresh with this uprated rear top arm inner bushing pair from Powerflex. By replacing the tired factory rubber at the inner pivot of the rear upper link with performance polyurethane, you get tighter rear-end control, crisper turn-in, more stable braking and consistent alignment under load. Ideal for fast road and track day use, and a brilliant long-term fix for vague steering feel and inner edge tyre wear on the back axle.

We have fitted this kit on our own builds and for customers, and the feedback is the same every time. More grip, less tramlining, a planted rear end and a genuine step up in confidence. Fit once, enjoy for years.
