The SPL Parts Eccentric Lockout Kit replaces Mazda's stock eccentric bolts to keep rear camber from shifting under heavy cornering, preserving alignment and handling. CNC-machined 6061-T6 aluminum plates and zinc-plated grade 10.9 bolts and locknuts deliver a zero-slip connection; one kit includes washers and bolts for both camber arms. Requires adjustable control arms to adjust camber after installation. Sold complete for one car. Made in the USA. Fits 2006–2015 Mazda Miata MX-5 NC and 2003–2012 RX-8.
