Brembo 1HD.8001A3 GT Gran Turismo Big Brake Kit with Drilled Rotors

The Brembo 1HD.8001A3 is a complete Gran Turismo (GT) Big Brake Kit featuring cross-drilled rotors, engineered for drivers who demand motorsport-grade stopping power for both street and track use. Part of Brembo's world-renowned GT upgrade lineup, this big brake kit (BBK) delivers a significant braking performance upgrade over factory systems with race-derived technology in a complete, bolt-on package.

Key Features:

• Cross-drilled cast iron alloy rotors with zinc coating for corrosion resistance — drilled holes dissipate heat, clear water and debris, and help maintain a consistent rotor-to-pad contact surface
• Aluminum-alloy calipers with radial mounting and opposed pistons for even brake force distribution, greater stiffness, and uniform pad wear
• Differential piston bore design eliminates pad taper for consistent friction contact across the entire pad face
• Twin-seal caliper design prevents debris ingress and protects brake fluid from contamination
• Compatible with factory ABS and traction control systems for seamless integration
• Calipers available in powder-coat finishes including black, red, silver, and select applications in yellow
• Includes high-performance Ferodo FM1000 brake pads — sold as a complete, ready-to-install set
• Backed by Brembo's two-year warranty

Brembo's GT Big Brake Kits are developed from decades of motorsport engineering, including experience supplying braking systems to Formula 1 teams and the world's leading production car manufacturers. The GT kit brings that same engineering philosophy to performance street and track applications, with oversized rotors and multi-piston calipers that provide superior fade resistance and pedal feel compared to OEM systems.

Installation Notes: Wheels of 17 inches or larger are typically required to accommodate the larger rotor diameter. Verify wheel backspacing and clearance prior to ordering. Installation instructions are included with the kit. Note: Brembo Big Brake Kits are custom made to order and are non-returnable.
