Sharpen your E46 Compact rear-end response with premium polyurethane arm bushes

Give your BMW E46 Compact the rear axle precision it deserves with this polyurethane inner bush set for the upper control arm. Part number PFR5-4617 replaces the factory rubber insert at the inner pivot of the rear upper link to stop unwanted movement, keep geometry stable and deliver confident, consistent handling on British roads.

This kit directly substitutes BMW reference 33321092247, providing a durable, oil and contamination resistant solution that maintains camber and toe under load. Expect cleaner turn-in, improved traction on corner exit and more predictable behaviour when pressing on.
