Push the boundaries of compact braking performance with the Wilwood GP200A Billet Caliper (Part #120‑17702). At just 0.9 lb, this is one of the lightest calipers available—perfect for tight-space applications such as sprint cars, Formula SAE, or custom builds.
Why This Caliper Excels:
Ultra-lightweight & rigid: Only 0.9 lb, CNC-machined from billet aluminum with FEA-optimized bridges, offering exceptional strength without bulk.
Precision performance: Features dual 1.25″ stainless steel pistons that resist corrosion and delay heat transfer for more consistent braking pressure.
Compact design, broad compatibility: With a 0.25″ rotor width and universal 2.38″ lug mount, it fits wheels with up to 11″ rotor diameter, front or rear.
Built to last: Finished with durable Type III hard anodize, and features spring-loaded SRS bridge plates that prevent pad rattle, reduce squeal, and resist wear.
Complete serviceability: Includes a central inlet (1/8‑27 NPT) and four-corner bleeds; compatible with multiple mounting orientations.
Ideal for performance builds where brake response, weight reduction, and installation flexibility matter.
