Brembo 1N2.9545A1 GT Front Big Brake Kit 6-Piston 405x34mm Slotted Black

The Brembo 1N2.9545A1 GT Series Big Brake Kit is a complete front axle brake system featuring 6-piston cast monobloc calipers with 405x34mm 2-piece slotted rotors in black. Designed for the 2018+ Audi RS5 (B9), this high-performance brake upgrade delivers superior stopping power and heat management for both street and track applications.

At the core of this system are precision-engineered aluminum calipers with monoblock construction from cast aluminum, ensuring unparalleled rigidity and minimizing deformation under intense braking conditions. The calipers are equipped with differential piston bores to eliminate pad taper, while a twin seal design prevents debris from entering and protects the brake fluid from contamination. The powder-coated black finish provides both corrosion resistance and aggressive styling.

The kit features two-piece floating disc construction with an exclusive venting system that enhances cooling capacity, reducing the risk of thermal shock-related cracking by 40%. The Type-1 slotted rotors feature 8 straight machined slots, providing enhanced cooling, degassing, initial bite when pressing the brakes, and excellent pedal feel and modulation. The billet aluminum hat is application-specific and individually machined to engineering specifications.

Each kit includes high-performance brake pads formulated with specific friction materials, TUV/DOT homologated metal-braided brake hoses for durability and reliability, plus adapter brackets and high-quality fastener hardware. The system ships pre-assembled with all necessary hardware included for easier installation.
