Brembo 1N2.9003AR GT-R Big Brake Kit Monobloc Caliper Upgrade System

The Brembo GT-R Big Brake Kit represents the pinnacle of high-performance braking technology, engineered with decades of racing expertise. Designed for enthusiasts who demand exceptional performance on both street and track, this system delivers professional-grade stopping power with a lighter, more responsive feel than traditional cast caliper systems.

Premium Monobloc Construction:

The GT-R system features precision-machined monobloc calipers crafted entirely from billet aluminum, providing superior stiffness and thermo-mechanical resistance critical for high-performance applications. This advanced construction achieves up to 10 percent weight reduction compared to cast versions while delivering the unmistakable appearance of a professional racing brake system. The nickel-plated finish offers enhanced corrosion resistance and an aggressive, premium aesthetic.

Advanced Heat Management:

Each caliper incorporates pistons with stainless steel inserts that create an additional thermal barrier, virtually eliminating brake fade even during maximum-effort track sessions. The two-piece floating rotor design reduces unsprung weight while accelerating heat dissipation, ensuring consistent performance lap after lap. Directionally vented and slotted rotors optimize cooling and pad bite characteristics.

Complete System Includes:

• Forged 4, 6, or 8-piston racing calipers with sequentially sized pistons for balanced pressure distribution
• Two-piece floating hat and rotor assemblies with slotted, directionally vented design
• High-performance brake pads available in street or race compounds
• DOT and TÜV certified Goodridge stainless steel 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-quality hardware
• All necessary components for seamless installation

The GT-R system delivers reduced brake fluid absorption and a noticeably stiffer pedal feel, providing consistent clamping force and precise modulation that serious drivers demand. Professional wheel fitment verification is required prior to installation to ensure proper clearance.
