Description

The Wilwood SX6R/ST forged six-piston caliper provides heavy-duty stopping power for road racing. It features Thermlock® pistons for ultimate heat protection and extreme durability. Radial mounting, multiple piston volume options, and a rotor diameter range up to 15.00" offer versatility. The body is stress-flow forged from premium aluminum alloy, realigning the internal grain structure to flow with the caliper's contour, eliminating stresses from machining. This results in superior clamping efficiency and ultimate strength against fatigue, stresses, and distortion under load.
