Wilwood GP320 Front Brake Kit with 4-Piston Caliper and Drilled Scalloped Rotor, Part 140-11773

Upgrade your sprint car braking system with the Wilwood GP320 Front Brake Kit, Part 140-11773. Designed for applications using a sprint car spindle, this complete front brake package combines a lightweight aluminum 4-piston caliper with a drilled and scalloped steel rotor for dependable stopping performance, consistent control, and efficient heat management. The gray anodized caliper finish adds durable corrosion resistance and a clean, professional appearance.
The Wilwood GP320 system is engineered for competition-focused use where braking response, weight control, and repeatable performance are essential. Its 4-piston design distributes clamping force evenly across the rotor, helping promote stable pad wear and predictable pedal feel. The drilled and scalloped rotor design supports cooling and reduces unnecessary rotating mass while maintaining the strength required for demanding racing conditions.
This Wilwood front brake kit is supplied as an application-specific solution for sprint car spindle setups, simplifying the process of matching the caliper and rotor components to the intended chassis configuration. Verify spindle, wheel, rotor, and brake clearance requirements before installation to ensure proper fitment. The kit is not air restricted and is not designated for truck freight shipping.
