SPL Rear Adjustable Toe Arms - E82 1M, E9X M3
Lightweight, tubular arms with premium FK bearings for toe adjustment and ultimate precision on track
The factory rear toe arms use rubber bushings that deflect a lot under extreme loads. The factory adjustment method of an eccentric washer and bolt is also not as precise as you want for a track alignment. Like a lot of parts they are well-suited for street use but not up to the task for serious track cars.
These tubular race arms are much more precise and use spherical bearing rod ends for zero play once set.
Standard: re-use your original eccentric mounting bolt and washer. This creates a "double-joint" eccentric mount that could be confusing or allow the settings to shift under hard use.
with Lockout Kit (recommended): new hardware that is not eccentric and sets the toe in place. The only toe adjustment is with the tube itself.
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.
SPL racing suspension parts are designed and manufactured in the USA from premium materials. SPL has a foundation in road racing, time trials, and drift competition which require precise suspension and alignment settings that can only come from spherical and solid mounts. Their parts are made with high-grade aluminum and titanium and use CNC machining and advanced production techniques to achieve to tight tolerances and light weight.
