Maximize the suspension set-up on your Mazda with these race ready adjustable rear lower control arms, camber lockout plates, and extended range toe cams from SPC. Specifically designed for performance applications, these arms include the xAxis sealed flex joint, exclusive to SPC. The xAxis performs like monoballs, but equipped with non-metal bushings which will provide a longer service life than OE bushings. These arms combine xAxis flex joints with forged steel receivers and straight-arm construction to minimize compliance under load. Included lockout plates will replace the OE camber cams to give you that extra assurance that your camber is locked in.
