Brembo 1T3.9515A1 GT Series Big Brake Kit 6-Piston 405x34mm 2-Piece Slotted Type-3 Rotor

The Brembo 1T3.9515A1 Gran Turismo (GT) Big Brake Kit is a complete, high-performance front braking upgrade engineered for drivers who demand race-inspired stopping power on both the street and the track. Featuring a 405mm x 34mm 2-piece slotted Type-3 disc paired with a 6-piston cast monobloc radial-mounted caliper, this kit delivers a dramatic improvement in braking force, fade resistance, and pedal feel over the factory brake system.

Key Features:

• 6-Piston Cast Monobloc Caliper: Machined from a single piece of high-strength aluminum for maximum rigidity and minimal flex under hard braking
• 405mm x 34mm 2-Piece Slotted Type-3 Disc: Oversized 2-piece floating rotor construction with Type-3 slots to continuously clean the pad surface, dissipate heat, and eliminate gases for consistent braking performance
• Advanced High Carbon Alloy Disc Material: Corrosion-resistant plating provides long service life and a bold, aggressive appearance
• Vented Curved 48-Vane Design: Maximizes airflow through the rotor to keep brake temperatures in the optimal operating range during demanding use
• Floating H-Bobbin with Anti-Rattle Spring: Precision disc-to-hat mounting system allows proper thermal expansion while eliminating vibration and noise
• High-Performance Brake Pads: Application-specific friction compound included for immediate street and track readiness
• Stainless Steel Braided Brake Lines: Proprietary Brembo lines by Goodridge reduce fluid expansion for a firmer, more responsive pedal
• CNC Billet Caliper Adapters & Hardware: All necessary mounting brackets and fasteners included for a complete bolt-on installation
• Full ABS & Traction Control Compatibility: Designed to integrate seamlessly with factory master cylinder, ABS, and stability control systems

The Brembo GT Big Brake Kit is built to bolt directly onto the vehicle's original suspension with no modifications required. Whether navigating daily commutes or pushing hard on a closed circuit, the 1T3.9515A1 delivers the consistent, confident braking performance that Brembo's motorsport heritage demands.
