Description

StopTech's new generation of calipers utilizes late model short tracking racing experience to provide a strong, lightweight caliper. The C43 caliper features a DR21 pad shape with approximately 11% more volume than ST40 caliper pads, and uses 36mm / 42mm piston bores for Subaru BRZ / Scion FR-S applications. It also allows for easy pad changes and includes StopTech SR race pads. The 2-piece disc assembly provides appropriate float for thermal expansion, enhancing performance and durability.
