Description
Increase rear suspension precision and improve handling consistency with the MMX Performance OEM Rear Toe/Traction Arm Bearing Set for BMW G8X and F8X M models. Designed as a direct OEM-fit upgrade, these high-performance precision pillow ball bearings replace the factory rubber bushings in the rear toe and traction arms, eliminating unwanted suspension deflection for improved chassis control, more consistent alignment, and enhanced driver confidence.
During hard acceleration, braking, and aggressive cornering, the factory rubber bushings flex under load, allowing changes in rear suspension geometry that can negatively affect stability, handling precision, and tire wear. The MMX Performance Rear Toe/Traction Arm Bearing Set replaces this compliant rubber with rigid rubber-booted precision pillow ball bearings, maintaining consistent rear toe geometry throughout suspension travel for more predictable handling, increased rear-end stability, and improved tire contact.
Each bearing assembly is CNC-machined from billet 6061-T6 aluminum, providing exceptional strength while remaining lightweight and corrosion resistant. The integrated protective rubber boot helps shield the precision bearing from dirt, moisture, and road debris, ensuring long-lasting durability in both daily driving and demanding track environments.
Installation is a direct OEM-fit replacement requiring no cutting, drilling, or permanent vehicle modifications, making it an ideal suspension upgrade for enthusiasts seeking sharper handling while maintaining factory mounting locations.
Important: Complete vehicle bearing upgrades require additional components depending on your current suspension configuration.
