Deliver sharper steering, improved stability, and lasting performance by replacing deflect-prone OEM rubber.

Welcome to the MMX Front Control Arm Spherical Bushings for the BMW F2x F3x platform — specifically BMW M135i, M235i, 335i, 435i, M140i, M240i, 340i and 440i. We make the products we run on our own vehicles, and this one delivers exactly what we expect from a true motorsport-grade solution.

These bushings are built to maintain precise wheel alignment under braking and hard cornering, both on the road and the track. By replacing the soft OEM rubber bushings — which deflect, wear, and fail under stress — we’ve eliminated the play and instability that hold back performance. What you get is sharper turn-in, improved steering feedback, and a more connected feel through the wheel and chassis.

Crafted from anodised 7075 aluminium paired with stainless steel spacers to withstand tough road conditions. Inside, a strong spherical bearing ensures long-lasting performance and reliability, far beyond what lower-cost options can offer. To protect the bearing during install, we’ve included a 3D printed press tool for a safe and damage-free fit.

This upgrade helps preserve tyre life and performance by keeping front toe stable under extreme conditions — meaning more grip, better tyre temps, and less wear during aggressive driving.

Fitting Note: A hydraulic or fly press is required for installation. We recommend professional fitting.
