Powerflex Black Series Track Front Wishbone/Lower Control Arm to Chassis Bushes for BMW 4 Series F32 F33 F36 - PFF5-1902BLK

Powerflex Black Series PFF5-1902BLK Polyurethane Front Arm Inner Bush Kit for BMW F32 F33 F36

Transform the front end response of your BMW 4 Series F32, F33 and F36 with the PFF5-1902BLK Black Series polybush kit. Designed for serious grip and repeatable handling on track days and fast road use, these uprated polyurethane front arm inner bushings clamp the lower arm to the body more securely to reduce flex, hold alignment and deliver crisp, confidence-inspiring steering.

Built in the Black Series 95 Shore A compound and engineered to be 8% stiffer than the factory rubber item, this kit resists deflection under heavy braking and cornering, helping to maintain camber and toe settings for cleaner turn-in and improved mid-corner stability. Expect sharper feedback through the wheel, better stability over kerbs and more consistent geometry when pushing hard.

We run these on our own cars and customer builds, and the feedback has been outstanding. Quicker steering response, more precise front-end feel and a noticeable improvement in how the car tracks under load. If you are chasing lap-time or want a tougher, longer-lasting alternative to OE rubber, this is a proven upgrade.
