SPL Race Rear Adjustable Upper Arms (Wishbone & Guide Link) - F8X M2/M3/M4

These tubular aluminum race arms use spherical bearings for much greater precision and strength than the stock arms. The original factory arms use pliable rubber bushings at both ends that are not at all suitable for track use. These arms are lightweight tubular aluminum with adjustable ends for dialing in alignments. One upper arm on each side can be used for camber adjustment in addition to the factory eccentric adjuster on the lower arms.

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