Brembo 1N2.9503AR GT-R Big Brake Kit High Performance Upgrade System

The Brembo GT-R Big Brake Kit represents the pinnacle of high-performance braking technology, combining decades of racing expertise with street-legal engineering. Designed for enthusiasts who demand exceptional stopping power both on the street and track, this system delivers professional-grade performance with remarkable precision and consistency.

Premium Monobloc Caliper Design:

At the heart of this system are Brembo's precision-machined monobloc calipers, crafted entirely from billet aluminum. This construction method provides superior stiffness, reduced weight (up to 10% lighter than cast versions), and enhanced thermo-mechanical resistance crucial for extreme driving conditions. The calipers feature sequentially-sized pistons with stainless steel inserts that create an additional heat barrier, virtually eliminating brake fade during aggressive driving sessions.

Advanced Two-Piece Floating Rotor System:

The kit includes Brembo's two-piece floating brake rotors with slotted and directionally-vented designs. This floating hat-and-rotor assembly reduces unsprung weight for improved handling response while dissipating heat more efficiently than single-piece designs. The result is consistent braking performance even during extended high-temperature use.

Complete System Includes:

• Forged 4, 6, or 8-piston racing calipers with sequentially-sized pistons for optimal pressure distribution
• Ventilated titanium piston inserts forming an additional heat barrier (application-dependent)
• Two-piece floating hat and rotor assemblies with directional venting
• Slotted performance rotors for improved wet and dry braking
• DOT and TUV-certified Goodridge stainless steel brake lines with lifetime guarantee
• High-performance brake pads available in street or race compounds
• Floating anti-rattle rotor hardware originally developed for the McLaren F1
• Precision-machined billet mounting brackets with aircraft-quality hardware
• Complete installation hardware for seamless fitment

Superior Finish and Durability:

Each caliper features a nickel-plated finish that provides enhanced corrosion resistance while delivering an aggressive, premium appearance. The low-absorption caliper design maintains consistent brake fluid characteristics and delivers a firm, responsive pedal feel that inspires confidence during spirited driving.

Important Note: Proper wheel clearance measurement is critical for fitment. Verify your wheel dimensions meet the minimum clearance requirements before installation to ensure proper caliper clearance and safe operation.
