Brembo 1ND.9005A3 GT Series Big Brake Kit 6-Piston Slotted Type 3 Rotors

The Brembo 1ND.9005A3 is a complete GT Series Big Brake Kit engineered for drivers who demand race-proven stopping power on the street or track. Part of Brembo's legendary Gran Turismo (GT) performance braking lineup, this kit delivers a significant upgrade over factory braking systems through advanced caliper technology, high-capacity rotors, and premium friction materials.

Key Features:

• 6-Piston Monoblock Calipers — Cast from a single billet of high-grade aluminum for maximum rigidity and minimal deformation under hard braking
• Type 3 Slotted 2-Piece Rotors — Directionally vented, slotted iron disc mounted to a lightweight billet aluminum hat to reduce unsprung rotating mass
• High-Performance Brake Pads — Included pads are formulated for aggressive street and track-day use, providing strong initial bite and fade resistance
• DOT/TUV-Approved Braided Stainless Steel Brake Lines — Goodridge-sourced lines provide consistent pedal feel and superior durability over OEM rubber hoses
• Aircraft-Quality Hardware — All mounting brackets, adapters, and fasteners are included for a complete installation
• Improved Thermal Management — Enlarged rotor diameter and advanced venting significantly increase thermal capacity, reducing the risk of brake fade during repeated high-speed stops
• Reduced Unsprung Weight — Two-piece floating rotor design with aluminum center hat lowers unsprung and rotating mass, improving suspension response and handling dynamics

The Brembo GT Big Brake Kit (BBK) is designed and validated through Brembo's extensive motorsport engineering resources, ensuring each component meets strict quality and performance standards. The complete kit ships ready to install and includes all necessary hardware, brake pads, and brake lines.
