Brembo 2P3.9045AR GT-R Big Brake Kit Monobloc Caliper 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 using knowledge accumulated through years of racing brake engineering, this exclusive system delivers professional-grade performance in a street-legal package.

Advanced Caliper Design:

The GT-R system features forged monobloc calipers with 4, 6, or 8 sequentially-sized pistons, machined entirely from billet aluminum. This construction method delivers up to 10 percent weight reduction compared to cast versions while providing superior stiffness and thermo-mechanical resistance. The pistons incorporate stainless steel inserts that create an additional heat barrier, virtually eliminating brake fade even during maximum-limit driving. The nickel-plated finish provides enhanced corrosion resistance and an attractive appearance.

Two-Piece Floating Rotor Technology:

The kit includes Brembo two-piece floating hat and rotor assemblies that reduce unsprung weight and dissipate heat more efficiently than one-piece designs. The slotted, directionally-vented rotors are engineered for optimal cooling and consistent performance under extreme conditions.

Complete System Includes:

• Forged monobloc racing calipers with sequentially-sized pistons
• Ventilated titanium piston inserts for additional heat barrier protection
• Two-piece floating hat and rotor assemblies
• Slotted and directionally-vented brake rotors
• DOT and TÜV certified Goodridge stainless steel brake lines with lifetime guarantee
• High-performance brake pads available in street or race compounds
• Floating anti-rattle rotor hardware developed for the McLaren F1 road car
• Billet mounting brackets with aircraft-quality hardware
• All necessary installation hardware for seamless fitment

This system delivers reduced brake fluid absorption and a stiffer pedal feel, providing consistent clamping force for drivers seeking maximum performance. The lightweight construction and advanced materials ensure reduced unsprung weight while maintaining the structural integrity required for track use.

Important Notes:

• This kit eliminates parking brake function
• Wheel clearance measurement is critical for proper fitment—verify wheel dimensions before installation
• Designed for select high-performance applications including Porsche, Ferrari, BMW, Corvette, and Camaro
