The MMX Front Control Arm Spherical Bushings are a must-have upgrade for BMW F2X and F3X models, including the M135i, M235i, 335i, 435i, M140i, M240i, 340i and 440i. Designed to replace the weak OEM rubber bushings, these motorsport-grade units deliver sharper steering, improved stability, and precise alignment under the toughest conditions.
By eliminating deflection and wear-prone rubber, these bushings allow the suspension to maintain accurate wheel alignment under heavy braking and hard cornering. The result is crisper turn-in, improved steering feedback, and a more connected feel on both road and track.
Each set is crafted from anodised 7075 aluminium with stainless steel spacers, paired with a high-strength spherical bearing for durability and long-lasting performance. For added protection, the kit includes a 3D printed press tool to ensure safe, damage-free installation.
This upgrade not only enhances performance but also helps preserve tyre life by keeping toe settings stable, ensuring better grip, consistent tyre temperatures, and reduced wear during aggressive driving.
