Brembo 1N3.9031AR GT-R Big Brake Kit High-Performance Racing Caliper System

The Brembo 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. This premium brake system combines race-proven design with cutting-edge materials to deliver uncompromising performance in the most demanding conditions.

Advanced Caliper Technology:

At the heart of this system are Brembo's precision-machined monobloc calipers, milled entirely from billet aluminum. This construction method provides superior stiffness, reduced weight (up to 10% lighter than cast versions), and enhanced thermo-mechanical resistance compared to traditional cast calipers. The sequential piston sizing optimizes pad wear and pressure distribution, while titanium piston inserts create an additional heat barrier that virtually eliminates brake fade during aggressive driving and track sessions.

Two-Piece Floating Rotor Design:

The kit features Brembo's advanced two-piece floating rotor assemblies with directionally vented, slotted rotors that reduce unsprung weight and dissipate heat more efficiently than one-piece designs. The floating hat and rotor configuration allows for thermal expansion without stress, maintaining consistent performance even under extreme temperatures. Anti-rattle hardware, originally developed for the McLaren F1 road car, ensures quiet operation and long-term durability.

Complete System Includes:

• Forged monobloc racing calipers with 4, 6, or 8 sequentially-sized pistons
• Ventilated titanium piston inserts for superior heat management
• Two-piece slotted and directionally vented rotors
• High-performance brake pads available in street or race compounds
• DOT and TÜV certified Goodridge stainless steel brake lines with lifetime guarantee
• Precision-machined billet mounting brackets with aircraft-quality hardware
• Anti-rattle rotor hardware for smooth, quiet operation
• Complete installation hardware for seamless fitment

Premium Finish and Engineering:

The calipers feature a nickel-plated finish that provides excellent corrosion resistance while delivering an attractive, race-inspired appearance. Stainless steel piston inserts minimize brake fluid absorption and deliver a firm, consistent pedal feel with improved clamping force modulation. The GT-R system's lighter, slimmer profile compared to standard Brembo GT calipers reduces unsprung weight for improved handling response.

Designed for select high-performance applications including Porsche, Ferrari, BMW, Chevrolet Corvette, and Camaro platforms. Professional installation recommended. Wheel clearance verification required before installation to ensure proper fitment with your specific wheel design.
