Product Description

The Wilwood 120-17702 GP200 caliper is an ultra-lightweight performance component engineered for applications where space is at a premium. Weighing just around 0.90 lb, its CNC-machined billet design offers exceptional strength without the bulk, making it perfect for racing vehicles, formula-style builds, and compact installations.

Equipped with two 1.25" stainless-steel pistons, this caliper provides firm and responsive pedal feel while resisting corrosion and delaying heat transfer. The SRS bridge plates reduce pad rattle and vibration, and the internal fluid passages along with four-corner bleeds give flexible mounting options.

Its compact dimensions and lug-mount configuration make it highly versatile - but due to its unique sizing, you must confirm rotor compatibility (especially width) and mounting geometry before proceeding with an installation. With the right setup, the 120-17702 delivers impressive stopping performance in a minimal footprint.
