Product Details
Wilwood's GP320 System starts with a focus on heat management, utilizing specially treated Super Alloy lightweight steel alloy rotors. Unlike ceramic coatings that can flake away under high heat, Wilwood’s Super Alloy material is designed to control heat transfer and provide a durable friction surface that holds up through long, demanding duty cycles without needing recoating. This advanced material helps ensure consistent performance when you need it most.
The system also features Wilwood’s competition-proven dynamic rotor mount system. This design uses a lightweight billet alloy plate with a t-nut system that isolates thermal stress and distortion at the rotor mounting points. This means the rotors stay flatter and run truer, eliminating any possibility of pad knock-back or deflection, which is critical for maintaining positive pedal feel and control during intense racing conditions. The GP320 billet caliper itself has four small pistons that work together to provide balanced distribution of pad load, leading to improved response and longer pad wear.
This kit includes the GP320 billet aluminum 4-piston calipers, Super Alloy rotors, dynamic mount rotor plates, Wilwood 6211-CM brake pads, and a rigid caliper mounting bracket with premium grade fasteners and shim washers for secure, deflection-free mounting. It's built for serious performance where fade-free stopping power is paramount.
