MMX Performance F8X Front Control Arm Spherical Bearing Set

Welcome to the MMX Front Control Arm Spherical Bushings for the BMW F8x platform — specifically BMW F87 M2, F80 M3 and F82 M4. 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 anodized 7075 aluminum 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 tire life and performance by keeping front toe stable under extreme conditions — meaning more grip, better tire temps, and less wear during aggressive driving.

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