Brembo 1P1.8505AR 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 racing expertise. Designed for enthusiasts who demand exceptional performance both on the street and track, this system delivers race-proven stopping power with superior heat management and reduced weight.

Advanced Caliper Design:

The GT-R system features lightweight monobloc calipers machined entirely from billet aluminum, providing up to 10 percent weight reduction compared to cast versions while delivering increased stiffness and superior thermo-mechanical resistance. The calipers utilize sequentially sized pistons with stainless steel inserts and ventilated titanium piston inserts that create an additional heat barrier, virtually eliminating brake fade during aggressive driving. The nickel-plated finish provides enhanced corrosion resistance and a premium appearance.

Two-Piece Floating Rotor Technology:

The kit includes Brembo's two-piece floating hat and rotor assemblies with directional venting and slotting. This design reduces unsprung weight for improved suspension response while dissipating heat more efficiently than one-piece rotors. The floating rotor hardware was originally developed by Brembo for the McLaren F1 road car, ensuring quiet operation without rattle.

Complete System Includes:

• Forged monobloc racing calipers with sequentially sized pistons (4, 6, or 8-piston configurations depending on application)
• Two-piece slotted and directionally vented floating rotors
• 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 aircraft-quality hardware
• Complete installation hardware for seamless fitment

The GT-R system delivers reduced brake fluid absorption and a firmer pedal feel for consistent clamping force and precise modulation. Designed to fit select applications including Porsche, Ferrari, BMW, Corvette, and Camaro platforms. Proper wheel clearance measurement is essential for fitment verification.
