Powerflex PFF5-5601M3 Polyurethane Front Wishbone/Lower Control Arm Rear Bush (FCAB) with Aluminium Outer - BMW E46 3 Series M3 - Pair

Uprated Front Arm Rear Mounts with Alloy Housing for BMW E46 M3

Transform front-end response on your BMW E46 M3 with this pair of Powerflex front control arm rear mounts, part number PFF5-5601M3. Featuring a hard-anodised alloy outer shell and a low-friction polyurethane centre, this E46 M3-specific FCAB upgrade delivers razor-sharp steering feel, tighter turn-in and rock-solid braking stability for fast road and track day use.

We run these on our own builds and many customer cars. The difference in front axle precision, mid-corner support and feedback is immediate, with excellent refinement for everyday use. It is a direct-fit performance replacement for the M3’s thicker front arm and installs into the original carrier for an OE-like finish with motorsport-grade control.
