Brembo 1M3.9042AR GT-R Big Brake Kit High Performance Track System

The Brembo GT-R Big Brake Kit represents the pinnacle of high-performance braking technology, engineered for drivers who demand exceptional stopping power on both street and track. Developed by Brembo's High Performance Division using decades of racing experience, this system delivers race-proven performance in a complete bolt-on package.

Premium Monobloc Caliper Design:

The GT-R system features calipers machined entirely from billet aluminum, providing 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 monobloc or 2-piece calipers offer a slimmer profile and enhanced thermo-mechanical resistance. Titanium piston inserts create an additional heat barrier, virtually eliminating brake fade even under extreme track conditions. The nickel-plated finish provides corrosion resistance while delivering an aggressive, race-inspired appearance.

Advanced Two-Piece Floating Rotor System:

The kit includes Brembo's two-piece floating rotors with directional venting, designed to reduce unsprung weight and dissipate heat more efficiently than conventional one-piece designs. The floating hat and rotor assembly allows for thermal expansion while maintaining optimal rotor face integrity, ensuring consistent performance during repeated hard stops.

Complete System Includes:

• Brembo forged monobloc or 2-piece racing calipers with sequentially sized pistons
• Titanium piston inserts for enhanced heat protection (most applications)
• Two-piece slotted and directionally vented floating rotors
• 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 developed for McLaren F1 road car
• Billet aluminum mounting brackets with aircraft-grade hardware
• All necessary installation components for seamless fitment

This system delivers reduced brake fluid absorption, stiffer pedal feel, and consistent clamping force for maximum driver confidence. Designed for select applications including Porsche, Ferrari, BMW, Corvette, and Camaro platforms. Professional installation recommended, and wheel clearance verification is required prior to installation.
