Powerflex PFF5-4001 Black Series Front Lower Control Arm Rear Bush Kit for BMW 2 Series M2 F87 2016-2021 – Polyurethane Tension/Thrust/Caster/Wishbone Arm (Radius Rod) Suspension Bushings to Chassis – 2 Bushes

Powerflex Black Series Front Arm Rear Bush Kit for BMW M2 F87 – PFF5-4001

Transform the front end of your BMW M2 F87 with this Powerflex Black Series bush kit, part number PFF5-4001. Engineered for drivers who want sharper steering, stronger braking stability and consistent geometry under hard use, these high-performance polyurethane bushes replace the soft factory rubber that allows unwanted arm movement.

Built from Powerflex Black Series material for track-capable precision, the bushings are approximately 18 percent firmer than OE. The result is crisper turn in, improved mid-corner stability and repeatable alignment control on fast road and circuit use, while keeping NVH well managed compared to tired original bushes.
