SPL Parts rear lower trailing arms replace the flimsy stamped steel factory arms with 6061-T6 billet aluminum, anodized black and assembled with zinc plated class 10.9 metric hardware. Each arm weighs 0.75 lbs (0.34 kg), roughly 35% less than the OEM piece, so unsprung mass at the rear corner drops and the dampers have less weight to control over bumps. Under hard acceleration and braking the stamped OEM arm deflects several millimeters, which together with rubber bushing flex introduces rear bumpsteer and instability; the billet section holds its geometry instead. SPL rates the arms as having no impact on NVH.
