Minus Plus


The rear camber arm bushing is one of the most overlooked suspension compromises on the G8X and F8X M-car. Replace it right.

The MMX Performance OEM Rear Camber Arm Bearing Set replaces the factory rubber bushings in your rear camber arm with precision pillow ball bearings machined from billet 6061-T6 aluminum. Under load, rubber deflects. Pillow ball bearings don't. The result is consistent rear camber geometry through hard cornering and braking, which translates directly into more predictable handling, better tire contact, and tire wear that stops looking random.

The Problem With Rubber

Your factory rear camber arm bushings are designed to isolate vibration and noise. That's the right priority for a street car shipping from the factory. It's the wrong priority when you're pushing the car hard. Under cornering loads, those rubber bushings allow the camber arm to deflect, altering your rear geometry in real time. The MMX pillow ball design removes that compliance and gives you a fixed pivot point that holds position regardless of load.

OEM-Fit. Zero Permanent Mods.

These bearings install as a direct replacement for the factory rubber bushings. No drilling, no cutting, no custom brackets. Each bearing is rubber-booted to protect the pillow ball from moisture and road debris, so they hold up as well on a daily driver as they do on track. The installation is fully reversible if you ever want to return to stock.

Installation Notes

Direct OEM-fit bearing replacement. Professional alignment recommended after installation to verify rear camber settings.

  1. Raise and safely support the vehicle, then remove the rear wheels
  2. Remove the factory rear camber arm and press out the OEM rubber bushings
  3. Press the MMX pillow ball bearings into the camber arm
  4. Reinstall the camber arm using the factory mounting hardware and torque to spec
  5. Reinstall wheels, lower the vehicle, and schedule a professional alignment

A hydraulic press is required to remove the factory bushings and install the MMX bearings. Professional installation is recommended if you do not have access to a press.
