MMX Front Control Arm Upgrade Bushings For F2X/F3X BMW

Upgrade your F2x F3x BMW with MMX Front Control Arm Spherical Bushings for sharper handling and improved stability. Designed to maintain alignment under hard braking and cornering, they directly replace the soft OEM rubber bushings that quickly wear, delivering precise steering response and lasting performance on road or track.

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.
