Powerflex Caster-Adjustable Front Radius Arm Bushings for BMW M2, M3, and M4 – Precision Chassis-Mounted Suspension Upgrades Compatible with F80, F82, F83, and F87 Platforms

Description

This replacement component is manufactured using Powerflex Black Series material, increasing stiffness by 18% compared to the factory bush to better handle the higher loads experienced at this mounting point. The PFF5-4001G features a fixed 5mm offset, providing approximately ±0.5° of additional caster to enhance steering weight and feedback.

The added caster also generates increased negative camber during cornering, helping to maintain a larger tyre contact patch under load and improving grip through fast bends. For drivers who prefer a non-offset option, Powerflex also offer the PFF5-4001 bush without caster correction.
