Wilwood 15H-16502K PolyMatrix H Compound Racing Brake Pads for XRZ4R Calipers

Upgrade braking performance with Wilwood 15H-16502K PolyMatrix H Compound racing brake pads, designed for use with Wilwood XRZ4R calipers. These high-temperature pads deliver a high-friction compound engineered for demanding track and performance driving applications, providing strong stopping power and consistent pedal response under elevated brake temperatures.
The PolyMatrix H compound is formulated to support reliable friction performance during repeated hard braking. Its racing-oriented construction helps maintain predictable braking characteristics when standard pads may experience heat-related fade. With a 20.3 mm pad thickness, this set provides a durable friction material platform for high-performance braking systems while maintaining compatibility with the specified XRZ4R caliper application.
This Wilwood brake pad set includes four pads for a complete axle installation. The 15H-16502K part number helps ensure accurate product selection when replacing worn pads or preparing a performance vehicle for competition use. Confirm caliper and pad-shape compatibility before installation, and follow the vehicle and caliper manufacturer’s bedding, inspection, and maintenance procedures for best results.
