Brake Caliper
  • Caliper Piston Quantity: 2
  • Weight: 0.9 lb.
  • Rotor Thickness: 0.25 in.
  • Mount Hole Center To Center: 2.38 in.
  • Caliper Casting Material: Billet Aluminum

    Tight-fit applications like small-diameter wheels and lightweight race cars call for the GP200, CNC machined from billet at just 0.9 lb. while still using a standard 2.38 in. lug mount.

    GP200 Caliper Features:

    • FEA-optimized body strengthens the transition between piston housings and caliper bridges.
    • Heavy wall stainless steel pistons resist corrosion and slow heat transfer from the pads.
    • Replaceable stainless steel SRS bridge plates reduce pad-gouging wear and brake squeal.
    • Internal fluid passages and four corner bleed screws allow mounting in any position.
    • The Wilwood GP200 Lightweight 2 Piston Billet Aluminum Brake Caliper represents the newest lightweight (only .90 pounds) caliper specifically designed for tight fit applications while utilizing a standard 2.38" lug mount. The GP200 combines superior strength with a black anodized finish along with several new performance features. The strength of the GP 200 is a combination of process and design. GP200 calipers are fully CNC machined from premium grade alloy billet. The FEA generated body design incorporates a highly fortified transition between the piston housings and the bridges. Strengthening this critical area of the caliper has substantially increased its resistance to deflection and body separation under load.

      Structural deflection and volume displacement testing have proven the efficiency of this innovative design. Reductions in overall deflection, and the subsequent decreases in fluid volume displacement, translate to increased clamping efficiency with less pedal travel. The bottom line is a firm, responsive pedal with outstanding stopping power. The GP200 uses heavy wall stainless steel pistons to resist corrosion and slow the heat transfer from the pads. The heavy wall sectional thickness improves pedal firmness and adds to the overall clamping efficiency by eliminating piston backside deflection at higher system pressures.

      Every GP 200 caliper is also fitted with replaceable stainless steel SRS bridge plates. SRS plates eliminate the bridge wear caused by pad gouging to extend the service life of the caliper body. The spring-loading action of the SRS plates also eliminates pad rattle and dampens the vibration harmonics that contribute to squeal during engagement. The package is completed with internal fluid passages and four corner bleed screws that allow mounting in any front, rear, left, or right side position.
