Powerflex PFF5-1902G Polyurethane Front Wishbone/Control Arm to Chassis Suspension Bush Kit (Pair) - Camber Adjustable Eccentric Alignment/Camber Correction - BMW 1 Series F20 F21 Bushings

Polyurethane Front Wishbone To Body Camber-Adjustable Bush Kit

Part number: PFF5-1902G

Vehicle compatibility: BMW 1 Series F20 and F21

Upgrade the front axle with this camber-adjustable polyurethane bushing set and transform steering feel, stability, and front-end grip. Designed as a direct replacement for the tired factory rubber mount, PFF5-1902G uses an eccentric design to deliver on-car alignment adjustment of approximately ±0.5 degrees, letting you dial in extra negative camber for sharper turn-in, better cornering traction, and more even tyre wear.

Constructed from performance polyurethane that is around 8 percent firmer than the original insert, this reinforced bush reduces unwanted deflection under braking and cornering without the harshness you might expect. Expect crisper response, improved straight-line stability, and predictable handling on fast road or track-day use. Our team at MJ Modifications has fitted these frequently and we rate the upgrade highly. Customer feedback is consistently positive, especially around steering precision and reduced tramlining.
