What the package does
“
★★★★★
I installed the rear toe and camber arms on my E92 and the difference was immediate. Before I felt the rear wanting to step out especially through high speed corners but now it feels way predictable and connected.
Ro, E92 owner
01
Rear camber and rear toe are set at two different links.
02
On a lowered E9x M3, both move once the factory rubber deflects under load.
03
The camber arms hold the camber you set on the rack.
04
The toe arms stop the rear from steering itself under load and braking.
05
Together they remove compliance from the rear axle.

Engineering
A suspension arm fails three ways. The body cracks, the spacers gall and pound out, or the bearing wears. The materials were chosen to beat all three. Both kits share this build.
Arm body
~1.7×
stronger at yield than 6061 / 6082-T6
~69 ksi yield. Aerospace 7000-series alloy.
Misalignment spacers & studs
~4×
harder than aluminum spacers
~170 ksi, 40–44 HRC. No brinelling, no galling.
Spherical bearings
0
deflection. Rebuildable, not throwaway.
Zinc-plated chromoly body, hard-chrome ball.
Validation
Developed on our A90 Supra through South Florida heat, humidity, and rain, plus track use at Sebring on slicks. Every MME arm uses the same rod-end architecture and three materials. That durability carries to the E9x arms.
