MMX Performance G8X / F8X OEM Rear Toe/Traction Arm Bearing Set

Improve rear suspension precision on your BMW G8X or F8X M2, M3, or M4 with the MMX Performance Rear Toe/Traction Arm Bearing Set. Machined from billet 6061-T6 aluminum, these precision pillow ball bearings replace the factory rubber bushings to eliminate unwanted deflection, maintaining consistent rear toe geometry under load for improved chassis response, increased rear-end stability, and reduced tire wear.

Under hard acceleration, braking, and cornering, the factory rubber bushings allow the rear toe and traction arms to flex, altering suspension geometry and reducing precision. The MMX pillow ball bearing design removes this compliance, providing a fixed pivot point that maintains rear toe settings throughout dynamic driving. The result is more predictable handling, improved tire contact, and more consistent tire temperatures during both spirited street driving and track use.

Each bearing is machined from billet 6061-T6 aluminum and utilizes a rubber-booted pillow ball to protect the bearing from moisture and road debris while delivering the rigidity required for high-performance driving. Installation is a direct OEM-fit replacement requiring no cutting, drilling, or permanent modification.

Important: Full vehicle kits require 2× MMR55-1650 (this part) and 2× MMR55-1651 Rear Camber Arm Bearings. Vehicles already equipped with the MMX Adjustable Rear Toe Arms (MMR55-1609) require 1× MMR55-1650 and 2× MMR55-1651 Rear Camber Arm Bearings.
