Powerflex PFR5-1920 Rear Subframe Front Position Bush Insert Kit for BMW 2 Series F22 F23 – Polyurethane Suspension Bushings (Poly Bushes) – Rear Axle Carrier Mount – OEM Ref 33316792509

Sharpen your BMW’s rear-end stability with polyurethane subframe inserts

Transform the way your BMW handles with this rear axle carrier front-position insert kit. Designed to locate within the voids of the factory rubber mount, these high-performance polyurethane inserts dramatically cut subframe movement for cleaner turn-in, improved traction and a more planted feel under acceleration and braking.

Perfect for spirited road use and track day prep, this upgrade helps keep alignment consistent, reduces wheel hop and gives you the confidence-inspiring feedback your chassis deserves. We have fitted these in our own workshop and the result is a tighter, more precise rear end that customers love.
