Brembo 1M3.9045AR Gt-R Big Brake Kit

The Brembo GT-R Big Brake Kit represents the pinnacle of street and track braking performance, engineered with decades of racing expertise. This professional-grade brake system delivers exceptional stopping power and thermal management for high-performance driving enthusiasts who demand race-proven technology for both street and track use.

Advanced Caliper Technology:

The GT-R system features Brembo's forged monobloc calipers machined entirely from billet aluminum, offering superior stiffness and up to 10% weight reduction compared to cast versions. Available in 4, 6, or 8-piston configurations with sequentially sized pistons, these calipers provide optimal pressure distribution and clamping force. The pistons incorporate stainless steel or titanium inserts that create an additional heat barrier, virtually eliminating brake fade during extended high-performance driving.

Two-Piece Floating Rotor Design:

The kit includes Brembo's innovative two-piece floating rotor assemblies with directional venting and slotting. This design reduces unsprung weight while dramatically improving heat dissipation compared to one-piece rotors. The floating hat design allows for thermal expansion without warping, ensuring consistent performance lap after lap.

Key Features:

• Forged billet monobloc calipers with lighter, slimmer profile than standard Brembo GT calipers
• Sequentially sized pistons with stainless steel or titanium heat barrier inserts
• Two-piece floating rotor assemblies with slotted, directionally vented design
• Nickel-plated finish for enhanced corrosion resistance and appearance
• High-performance brake pads available in street or race compounds
• Precision-machined billet mounting brackets with aircraft-grade hardware
• Anti-rattle floating rotor hardware developed for the McLaren F1
• DOT and TÜV certified for street legality
• Reduced brake fluid absorption for consistent pedal feel

What's Included:

This complete big brake kit includes calipers, two-piece rotors, high-performance brake pads, mounting brackets, and all necessary hardware for installation. Brake lines are not included—OEM brake lines must be reused. Professional installation is recommended, and proper wheel clearance verification is required before installation.

Important Note:

Wheel fitment measurement is critical for proper installation. Verify wheel clearance specifications before ordering to ensure compatibility with your vehicle and wheel combination.
