Brembo 1MD.9003AR GT-R Series Big Brake Kit 380mm 6-Piston Monobloc

The Brembo 1MD.9003AR is a complete GT-R Series Big Brake Kit engineered for high-performance street and track applications. Drawing on Brembo's decades of motorsport development, this kit delivers a significant braking upgrade over OEM components with race-derived technology in a bolt-on package.

At the heart of the kit is a 6-piston monobloc caliper machined entirely from billet aluminum, providing exceptional rigidity and resistance to flex under extreme braking loads. The radial-mount caliper design ensures consistent, predictable pedal feel and superior stopping power. Individual pistons feature stainless steel radiators that minimize heat transfer to the brake fluid, reducing the risk of vapor lock and brake fade during aggressive driving.

The caliper body is nickel plated for long-term corrosion resistance and features the Brembo logo in CNC-machined red embossing for a distinctive, premium appearance behind the wheel.

Paired with the caliper are 2-piece floating 380mm x 34mm discs that reduce unsprung weight while dramatically improving thermal capacity. The floating disc design allows radial and axial movement to accommodate heat expansion, reducing the risk of warping and thermal cracking. The exclusive internal venting system improves cooling capacity and increases resistance to cracking from thermal shock.

Key Features:

• 6-piston billet aluminum monobloc caliper with radial mounting
• Stainless steel piston radiators for reduced heat transfer and fade resistance
