MMX Performance Front Control Arm Spherical Bearings G8X M2 / M3 / M4
The MMX Performance Front Control Arm Spherical Bearings for the BMW G87 M2, G80/G81 M3, and G82/G83 M4 replace the factory rubber control arm bushings with a precision CNC-machined housing and motorsport-grade spherical bearing assembly. By eliminating the compliance and deflection inherent in the factory rubber bushing, the MMX spherical bearing conversion provides a more direct connection between the front suspension and chassis.
Each bearing housing is CNC-machined from high-strength 7075 aluminum and anodized for long-term protection, then paired with stainless steel spacers and a high-strength spherical bearing. The spherical bearing allows controlled rotational and angular movement while significantly reducing the unwanted deflection found in the factory rubber bushing under braking and cornering loads.
On the BMW G8X chassis, reducing control arm bushing deflection improves steering response and helps maintain more consistent front suspension geometry under load. The difference is particularly noticeable during trail braking, initial turn-in, and sustained cornering, where more stable toe geometry and improved front tire control contribute to greater steering precision and predictable front-end response.
The MMX Performance Front Control Arm Spherical Bearings are designed for installation into the factory BMW front control arms and are directly compatible with OEM BMW part numbers 31108095667 (left) and 31108095668 (right). A dedicated 3D-printed press tool is included to assist with installing the spherical bearing assemblies into the original control arms without damaging the new components.
