Engineering & Technology

Billet CNC-machined from a single block of aerospace-grade aluminum, the XA8.31 features differential bore pistons (28/30/38mm) that progressively increase clamping force from leading to trailing edge, ensuring perfectly even pad wear across the entire friction surface.

Performance Upgrade

• Fixed Caliper Design: Eliminates flex and provides consistent pad-to-disc contact across all pistons, unlike factory sliding calipers
• Differential Bore Pistons: Progressively sized pistons distribute clamping force evenly, eliminating tapered pad wear
• Increased Disc Diameter: Larger swept area dramatically improves heat dissipation and braking torque
• Reduced Unsprung Weight: Lightweight aluminum construction improves suspension response and handling

Compatible Pad Compounds

Available pad options:

• Endless MX72
• Winmax W615

Brembo pad shape code: B24-B28 — use this code when ordering replacement pads.

RH Disc & Pad Options

Brake Discs:

• RH — 2-piece floating rotor with CNC-machined 7075-T6 aluminium bell

Brake Pads:

• Endless MX72
• Winmax W615
