Powerflex Polyurethane Rear Cradle Mount Inserts for BMW 1 Series F20 F21 2011-2019 - PFR5-1921

Sharpen your BMW 1 Series with a simple, high-value chassis upgrade. These Powerflex polyurethane rear cradle mount inserts slot into the voids of the original rubber mounts at the back of the rear subframe to curb unwanted movement, delivering tighter cornering, better traction and a more connected drive on British roads. Ideal for daily use and fast road setups, this is a smart way to add precision without pressing out the factory mounts.
