Brembo 1N3.9046AR GT-R Big Brake Kit High Performance Racing Caliper System

The Brembo 1N3.9046AR GT-R Big Brake Kit represents the pinnacle of high-performance braking technology, engineered specifically for drivers who demand exceptional stopping power on both street and track. Developed by Brembo's High Performance Division using decades of racing experience, the GT-R line delivers professional-grade braking performance for select high-performance vehicles including Porsche, Ferrari, BMW, Corvette, and Camaro applications.

Advanced Monobloc Caliper Design:

The GT-R system features precision-machined monobloc calipers available in 4, 6, or 8-piston configurations with sequentially sized pistons for optimal pressure distribution. Machined entirely from billet aluminum rather than cast, these calipers offer up to 10 percent weight reduction compared to standard versions while providing superior stiffness and thermo-mechanical resistance. The elegant nickel-plated finish delivers both enhanced corrosion protection and an aggressive racing aesthetic.

Two-Piece Floating Rotor Technology:

The included two-piece floating rotor assemblies reduce critical unsprung weight while dramatically improving heat dissipation during extreme braking conditions. These directionally vented and slotted rotors work in concert with the floating hat design to minimize thermal stress and maximize cooling efficiency, ensuring consistent performance lap after lap.

Complete System Includes:

• Brembo forged monobloc racing calipers with sequentially sized pistons (configuration varies by application)
• Ventilated titanium piston inserts providing an additional heat barrier to virtually eliminate brake fade
• Two-piece floating hat and rotor assemblies with directional venting and slotting
• High-performance brake pads available in street or race compounds
• DOT and TÜV certified Goodridge stainless steel braided brake lines with lifetime guarantee
• Floating anti-rattle rotor hardware originally developed for the McLaren F1 road car
• Precision-machined billet mounting brackets with aircraft-grade hardware
• Complete installation hardware for seamless fitment

Performance Benefits:

The stainless steel piston inserts create an effective thermal barrier that reduces brake fluid absorption, resulting in a firmer pedal feel and more consistent clamping force even during maximum-effort driving. The lighter, stiffer caliper design combined with reduced unsprung weight improves suspension response while delivering the stopping power needed to extract every last tenth of a second on track.

Important Fitment Note: Wheel measurement is critical for proper brake system clearance. Verify your wheel specifications before installation to ensure compatibility with this big brake kit.
