Brembo 1B1.8024A3 GT 4 Piston Front Big Brake Kit 355x32mm Drilled Rotors

The Brembo Gran Turismo (GT) 4 Piston Big Brake Kit delivers exceptional stopping power for both daily driving and high-performance street and track applications. Engineered specifically for 1978-1979 Porsche 930 models, this front brake upgrade features 355x32mm two-piece drilled rotors with silver calipers that bolt directly to your vehicle's original suspension without modification to the brake master cylinder or ABS system.

Complete System Includes:

• Four-piston fixed aluminum brake calipers in silver finish
• Two-piece vented brake rotors (355mm diameter x 32mm thick) with drilled surface
• High-performance brake pads
• Stainless steel braided brake lines
• Aircraft-quality mounting brackets and hardware

Premium Engineering Features:

• Cross-drilled holes are bi-angle chamfered at outer surfaces to minimize stress cracking during high-temperature operation
• Two-piece rotor design reduces unsprung weight while improving heat dissipation
• Corrosion-resistant coating on rotors eliminates rust and provides aggressive appearance through wheel spokes
• Fixed caliper design ensures even pad wear and consistent brake feel
• Fully compatible with factory brake master cylinder and anti-lock braking systems

Important Installation Note: Requires minor modification to OEM components. Wheel fitment measurement is critical before installation to ensure proper clearance with your specific wheels.

For matching rear brake appearance, Brembo Sport slotted or drilled rotors are available separately for applications without a dedicated Gran Turismo rear system.
