OVERVIEW

The Cusco Lightweight Rear Brake Caliper Bracket replaces the heavy factory cast iron components on the GR Corolla's rear knuckles. CNC-machined from high-strength billet aluminum, this replacement kit strips away critical unsprung weight directly from the rear axle assembly. By reducing unsprung mass, it allows the suspension to react faster to road imperfections and cornering inputs, delivering a performance-minded weight-reduction solution without compromising braking structural integrity.
