Brembo 1MD.9045AR GT-R Series Big Brake Kit

The Brembo 1MD.9045AR is a GT-R Series Big Brake Kit engineered to deliver professional motorsport-level braking performance for serious street and track driving applications. Part of Brembo's flagship GT-R lineup, this kit represents the pinnacle of the company's decades of racing expertise translated directly into a complete bolt-on upgrade.

At the core of the GT-R system are billet aluminum monoblock calipers featuring a radial multi-piston configuration. Unlike traditional two-piece cast calipers, the monoblock construction is machined from a single billet of aluminum, virtually eliminating flex under extreme braking loads and maintaining a consistent, confidence-inspiring pedal feel even during extended high-temperature use. Individual pistons incorporate stainless steel thermal inserts to minimize heat transfer to the brake fluid, reducing the risk of fade or fluid boil.

Key Features:

• Billet aluminum monoblock radial-mount calipers with multi-piston configuration
• Nickel-plated caliper finish for corrosion resistance and premium appearance
• Two-piece floating disc design reduces unsprung weight and dissipates heat rapidly
• Anti-noise floating disc hardware derived from Brembo's Formula 1 program
• High-performance brake pads with friction compounds suited for both street and track use
• Stainless steel braided brake lines included for improved pedal feel and durability
• CNC billet caliper adapter brackets and all necessary installation hardware included

The two-piece floating rotors feature an advanced venting system that increases resistance to thermal cracking caused by heat shock, while the floating hat design allows for thermal expansion without inducing rotor distortion. The result is consistent stopping power lap after lap, with reduced brake fade under the most demanding conditions.

Every Brembo GT-R Big Brake Kit ships as a complete package ready for installation, including calipers, rotors, brake pads, stainless steel brake lines, and all mounting hardware. No fabrication is required.
