Overview
Lock down your rear lower front hinge pin geometry with the Hot Racing Aluminum Rear Lower Front Hinge Pin Brace Arm Mount. CNC-machined from 6061 aluminum, this hinge pin brace mounts at the front position of the rear lower suspension, replacing the stock plastic and stamped aluminum hinge pin mount with a single rigid aluminum piece that locks the hinge pin in place.
Hinge pin walk under aggressive driving is a known source of inconsistent suspension feel; this aluminum brace eliminates that issue entirely. A secure M4 set screw maintains hinge pin position even under the most severe driving conditions, keeping rear suspension geometry consistent run after run.
