Brembo 2P3.9004AR GT-R Big Brake Kit High Performance Upgrade System

The Brembo 2P3.9004AR GT-R Big Brake Kit represents the pinnacle of braking technology, engineered for drivers who demand exceptional performance on both the street and track. Drawing from decades of racing experience, Brembo's High Performance Division designed the exclusive GT-R line to deliver professional-grade stopping power for select high-performance applications including Porsche, Ferrari, BMW, Corvette, and Camaro vehicles.

Advanced Caliper Technology:

The GT-R system features monobloc calipers machined entirely from billet aluminum, providing superior stiffness and lighter weight compared to cast versions—achieving up to 10 percent weight reduction. These forged calipers utilize sequentially sized pistons with stainless steel inserts that create an additional heat barrier, virtually eliminating brake fade even during maximum-limit and track driving conditions. The nickel-plated finish offers enhanced corrosion resistance while delivering an attractive, professional appearance.

Two-Piece Floating Rotor Design:

The system includes Brembo's two-piece floating brake rotors with directional venting and slotting for optimal heat dissipation. This floating hat and rotor design reduces unsprung weight while improving thermal management during aggressive driving. The anti-rattle rotor hardware was originally developed by Brembo for the McLaren F1 road car, ensuring quiet operation and precise rotor positioning.

Complete System Includes:

• Forged 4, 6, or 8-piston racing calipers with sequentially sized pistons and slimmer profile than standard GT calipers
• Ventilated titanium piston inserts forming an additional heat barrier (application-dependent)
• Two-piece floating slotted and directionally vented rotors for reduced unsprung weight
• High-performance brake pads available in street or race compounds
• DOT and TÜV certified Goodridge stainless steel brake lines with lifetime guarantee
• Billet mounting brackets with aircraft-quality hardware
• All necessary hardware for seamless installation

The GT-R system delivers reduced brake fluid absorption and a stiffer pedal feel, providing consistent clamping force for drivers seeking maximum performance. The combination of lightweight construction, advanced thermal management, and racing-derived components makes this system ideal for enthusiasts who want to extract every second from their vehicle's potential.

Important: Wheel measurement is critical for proper fitment. Verify wheel clearance specifications before purchase to ensure compatibility with your application.
