Caliper GM Metric 1.12 Piston .810in Rotor

The Caliper GM Metric 1.12 Piston .810in Rotor from WILWOOD delivers precision braking performance for street, strip, and track applications where OEM systems fall short. This brake caliper assembly is engineered for enthusiasts and professional mechanics building custom brake systems on GM platforms, particularly when upgrading from factory components to performance-grade stopping power. WILWOOD's metric calipers are industry standards for custom builds, resto-mods, and high-performance vehicle conversions where exact dimensional fitment and reliable repeatability are non-negotiable.

This caliper features a 1.12-inch piston diameter paired with a .810-inch rotor specification, a combination that balances clamping force distribution and thermal dissipation for consistent pedal response under sustained braking loads. The metric design ensures compatibility with modern GM brake line fittings and caliper mounting brackets, eliminating adapter complications common when mixing imperial and metric systems. WILWOOD calipers are constructed from high-grade ductile iron bodies with stainless steel pistons that resist corrosion and maintain dimensional stability across temperature cycles, critical for street cars exposed to salt and moisture or race vehicles experiencing extreme heat cycles.

Mechanics and fabricators building front or rear brake systems on Gen III/IV Corvettes, Camaros, Trucks, and LSx-powered swaps will find this caliper essential for custom brake line routing and pad selection flexibility. Installation requires brake line connection to the caliper ports and proper rotor pairing; verify your rotor diameter and thickness specs before ordering to ensure complete system compatibility. The 4.9-pound weight per caliper suits dual-caliper setups on single wheels or split-circuit configurations, making this an ideal foundation component for professional-grade brake system design.
