Rear adjustable toe arms for M2 (F87, G87), M3 (F80, G80), M4 (F82, G82).
The BimmerWorld View: The factory adjustment method of an eccentric washer and bolt is not as precise for a serious track alignment. To get a proper track alignment on the factory arms you run into a wall where you can either get the camber OR toe you want, but not both. These adjustable arms are there to give you the adjustment needed to get everything where you want it. We have included shims that can be used to adjust the REAR bump steer and dynamic toe change. They also eliminate the rubber bushings of the stock arms, reducing deflection and alignment variation.
This part replaces BMW part number 33322284534 (33 32 2 284 534) and is described as a rear wishbone (aka toe arm) for F87 M2, G87 M2, F80 M3 sedan, G80 M3 sedan, F82 M4 coupe, and G82 M4 coupe. This is an adjustable version with precision rod ends and bearing spacers that gives more tunability to your rear alignment than simple adjustable arms. These tubular race arms are much more precise and use FK spherical bearing rod ends for near-zero play once set.
+ Adjustable toe alignment AND tuning rear bump steer
+ lightweight tubular race arms are much lighter than factory
+ 6061-T6 aluminum rod
+ High-precision, low-friction Teflon-lined FK rod ends
+ Jam nuts for quick and easy adjustment and almost impossible to over-tighten
+ Replaces BMW part number 33322284534
The rear suspension has bump steer and it can be adjusted to change the car's behavior (toe change) under compression (acceleration or outside tire, aka bump) or extension (braking or inside tire, aka droop). With our arms and shims you can alter the behavior as a “road course” setup (stability under braking + rear steer) OR as a “launch” setup (stability under acceleration and straight-line grip), or mimic the factory setup (which is very stable in bump and droop).
Professional installation and setup very strongly recommended.
Made in the USA.
Also fits M2 CS Racing, F82 M4 GT4, and G82 M4 GT4, however, these were built to homologation rules and these arms will change that - be sure to consult with your series rules before use.
Designed for track/racing use only. Use of solid and spherical bushings will have more noise and harshness than any other material and are not recommended for street use.
You MUST have a Rear Lockout Kit that eliminates the factory eccentric washer. Any Lockout Kit will be compatible as long as it uses an M12 bolt (85-90mm length). See Related Items below for Lockout Kits we offer.
