Brembo 1MD.9005AR GT-R Series Big Brake Kit 6-Piston Monobloc Caliper 380mm 2-Piece Rotor

The Brembo 1MD.9005AR is a GT-R Series Big Brake Kit (BBK) representing Brembo's most advanced street and track braking system. Engineered from decades of motorsport experience, this front axle kit delivers a complete corner brake upgrade far beyond standard OEM braking performance.

GT-R Series Caliper:

• 6-piston billet monobloc caliper — machined from a single block of aluminum for maximum rigidity and minimal deformation under hard braking
• Radial mount design with nickel plating for superior corrosion resistance and long-term durability
• Individual pistons with stainless steel thermal insulators reduce heat transfer to brake fluid, minimizing fade and maintaining consistent pedal feel
• CNC-machined Brembo logo in red embossing

2-Piece Floating Rotor:

• 380mm diameter rotor with a two-piece floating disc assembly — cast-iron braking surface mounted to a lightweight billet aluminum hat
• Floating design reduces unsprung and rotating weight, improving suspension dynamics, acceleration, and braking response
• Directionally vented and cross-drilled for maximum heat dissipation and continuous pad surface refreshing
• Advanced venting system increases resistance to thermal shock cracking by over 40%

Complete Kit Includes:

• High-performance brake pads with sport-spec friction material suitable for street and track use
• DOT/TUV-approved Goodridge stainless steel braided brake lines
• Brembo-engineered CNC billet caliper mounting brackets and all necessary hardware
• Instruction manual and Brembo decals

Note: Some GT-R system installations may require modification or removal of the OEM dust shield or backing plate. Wheel clearance should be verified prior to installation.
