Key Features

This Brembo GTR Rear Big Brake System combines cutting-edge technology and superior materials to deliver exceptional braking performance:

• 4-piston monobloc aluminum calipers for enhanced rigidity and reduced deformation
• 15-inch (380x28mm) two-piece cross-drilled and slotted rotors for improved heat dissipation
• Exclusive venting system reducing thermal shock-related cracking by 40%
• Floating disc design with anti-rattle springs for noise reduction and rotor stability
• Brembo high-performance FM1000 brake pads optimized for consistent friction and modulation
• Durable TUV/DOT homologated stainless steel braided brake lines by Goodridge
• Complete axle set pre-assembled for ease of installation
• All necessary Brembo-engineered CNC billet caliper adapters and hardware included
• Corrosion-resistant plating on rotors for long-lasting appearance and performance

Construction & Design

The Brembo GTR system features monobloc calipers machined from a single billet of cast aluminum, ensuring exceptional strength and minimal flex during heavy braking. This design maintains consistent pad contact and pedal feel, even under extreme conditions. The rotors are constructed from an advanced high-carbon alloy with a corrosion-resistant finish, enhancing durability and thermal management.

The two-piece rotor assembly includes a floating disc mounted to a lightweight aluminum hat via D-bobbins and anti-rattle springs, allowing for thermal expansion and reducing the risk of warping. Cross-drilled and slotted surfaces improve heat dissipation and help evacuate brake dust and gases, maintaining optimal braking efficiency.

Performance & Sound

This brake system significantly improves stopping power and pedal modulation, reducing braking distances and increasing driver confidence. The high-performance pads and stainless steel braided lines contribute to a firm, responsive brake feel. The drilled and slotted rotors also help minimize brake fade during extended use, making this kit well-suited for both spirited street driving and occasional track use. While designed for performance, the system maintains a refined sound profile without excessive noise or vibration.
