Brembo 1M3.9044AR GT-R Big Brake Kit High-Performance Upgrade System

The Brembo GT-R Big Brake Kit represents the pinnacle of high-performance braking technology, engineered with decades of motorsport expertise. This premium brake system is designed for enthusiasts who demand exceptional stopping power both on the street and at the track, offering a professional-grade upgrade for select performance vehicles including Porsche, Ferrari, BMW, Corvette, and Camaro applications.

Advanced Caliper Technology:

The GT-R system features monobloc calipers machined entirely from billet aluminum, offering superior stiffness and up to 10 percent weight reduction compared to cast versions. Available in 4, 6, or 8-piston configurations with sequentially sized pistons, these calipers deliver consistent clamping force and precise modulation. The slim profile design maximizes wheel clearance while maintaining exceptional rigidity. Many GT-R calipers incorporate titanium piston inserts that create an additional heat barrier, virtually eliminating brake fade during extreme driving conditions.

Two-Piece Floating Rotor Design:

The kit includes Brembo's two-piece floating rotor assemblies with slotted, directionally vented rotors that reduce unsprung weight and accelerate heat dissipation. This proven design, originally developed for the McLaren F1 road car, incorporates anti-rattle hardware for quiet operation and longevity. The floating hat-and-rotor construction allows for thermal expansion while minimizing stress and warping.

Complete System Includes:

• Forged monobloc or 2-piece racing calipers with sequentially sized pistons
• Ventilated titanium piston inserts for enhanced heat resistance (application-dependent)
• Two-piece slotted and vented floating rotors for optimal cooling
• High-performance brake pads available in street or race compounds
• DOT and TUV certified Goodridge stainless steel braided brake lines with lifetime guarantee
• Billet aluminum mounting brackets with aerospace-grade hardware
• Anti-rattle rotor hardware for noise-free operation
• Complete installation hardware for seamless fitment

Premium Finish and Durability:

Each caliper features a nickel-plated finish that provides superior corrosion resistance and an attractive appearance. The stainless steel piston inserts minimize brake fluid absorption and deliver a firmer pedal feel with consistent response, even during extended track sessions.

Important: Proper wheel fitment verification is critical before ordering. Measure your wheel's inner dimensions carefully to ensure adequate clearance for the larger caliper and rotor assembly.
