Engineering & Technology

The XA5.T0 delivers an impressive 53.1 cm² piston area from just 4 pistons (38/44mm), rivaling many 6-piston designs. Proven in World Rally Championship competition, its forged monobloc construction at 2.7 kg handles extreme thermal cycling with ease.

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: B18/B19 — use this code when ordering replacement pads.
