Brembo 1B1.7003A3 GT 4-Piston Front Big Brake Kit 332mm Drilled Rotors

The Brembo GT 4-Piston Big Brake Kit (1B1.7003A3) delivers professional-grade stopping power for the 1989-1993 Ferrari 348. This complete front brake upgrade system features 332x32mm 2-piece vented rotors with drilled surface pattern and silver finish, paired with Brembo's renowned 4-piston fixed aluminum calipers.

Complete Performance Brake System

Each Gran Turismo brake kit is engineered as a direct bolt-on upgrade that integrates seamlessly with your vehicle's original suspension, stock brake master cylinder, and ABS system. The package includes high-performance aluminum calipers, large-diameter 2-piece vented rotors, performance brake pads, stainless steel braided brake lines, and aircraft-quality mounting brackets with all necessary hardware.

Advanced Rotor Design

The 332mm x 32mm 2-piece rotors feature cross-drilled holes with bi-angle chamfering at the outer surfaces to minimize stress cracking during high-temperature track use. All rotors include a corrosion-resistant coating that prevents rust while delivering an aggressive appearance through your vehicle's wheels. The drilled pattern enhances heat dissipation and wet-weather performance.
