This is a replacement XRAY Pre-Glued Brake Pad Set, and is intended for use with the XRAY RX8. This factory assembled brake pad set will provide consistent, precise braking. The high-precision, ultra-efficient steel brake pads are CNC-machined and precision ground on both sides for an ultra-smooth surface finish to guarantee maximum braking efficiency. The brake pad backing plates are heat-treated for maximum lifespan, while the high-grip brake pad material is specially bonded to the backing plates for high resistance to generated heat build-up.
