Powerflex PFR5-1921 Rear Subframe Rear Bush Insert Kit BMW 2 Series (F22, F23) Polyurethane Bushes, Set of 2 OEM Ref 33316792510 Diagram 21

Transform the way your BMW 2 Series turns in and puts power down with this uprated rear cradle insert set. Part number PFR5-1921.

This performance polyurethane insert pair is engineered to locate into the cavities of the factory rear axle carrier mounts on the BMW 2 Series F22 coupe and F23 convertible. By bracing the OEM rubber, these inserts control unwanted subframe movement, tighten up the back end and deliver the crisp, predictable handling keen drivers want on fast road and track. Expect cleaner direction changes, better traction out of corners and a more connected feel without resorting to full solid bushes.

We run these on our own builds and customer cars, and feedback is consistently positive. Drivers report improved stability under throttle and braking, more confidence mid-corner and less rear-end squirm. It is a simple, proven upgrade that complements coilovers, performance tyres and alignment tweaks.
