Subaru WRX STI Camber & Castor Arms - Rear Lower - SPL Parts - Titanium Series Adjustable - '15-'27. Precision rear lower control arms that deliver accurate on-car camber and motion-ratio tuning for your WRX/STI.

Designed to reduce dynamic alignment change and bushing bind, these arms manage spring, shock, and sway bar loads while sharpening feedback. Three-position shock and endlink mounts tune motion ratios and prevent endlink interference. A 4130 chromoly double adjuster with 5/8 in rod end delivers up to 1.375 in total length change, and 360° clamps enable quick, jam-nut-free tweaks. Lightweight 6061-T6 construction and titanium hardware complete a durable, track-proven package.
