SPL Race Rear Adjustable Trailing Arms - F22, F30, F32

Replaces the lower, forward arm in the F22 2-series, F30 3-series, and F32 4-series rear suspension. BMW calls it a "trailing arm" and uses rubber bushings that will deflect and twist under heavy load, which causes unwanted changes in the rear alignment. These aluminum arms use spherical FK rod ends to eliminate deflection and keep your alignment where you set it.

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. The stock factory trailing arm is designed to absorb impacts and deform. Using a more-solid piece like this race arm will transfer impact loads elsewhere and may cause other items to fail instead. If impacts with curbing or other vehicles may occur it may be best to leave the stock arm and only upgrade the bushings.

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. FK Spherical Bearings include a Teflon inner liner for quieter and longer service life. SPL Parts have a limited one year warranty.
