Brembo 1Q1.9634A2 GT Series Big Brake Kit Drilled Rotor Caliper - 412x38mm 2-Piece 8-Piston Red

The Brembo 1Q1.9634A2 is a front GT Series Big Brake Kit engineered for drivers who demand race-derived stopping power on the street or track. Featuring a 412mm x 38mm 2-piece drilled rotor paired with a monobloc 8-piston B-M8 red caliper, this kit delivers a dramatic upgrade in braking torque, thermal capacity, and pedal feel over stock components.

Key Features:

• Monobloc 8-Piston Caliper (B-M8): Machined from a single billet of cast aluminum for maximum rigidity and minimal flex under hard braking; finished in signature Brembo Red
• 412mm x 38mm 2-Piece Drilled Rotor: Oversized floating disc design improves heat dissipation and resists thermal shock; cross-drilled surface evacuates gases, dust, and debris from the pad contact zone
• 2-Piece Floating Rotor Construction: Aluminum hat with floating iron ring reduces unsprung weight and accommodates thermal expansion without warping
• High-Performance Brake Pads: Application-specific friction material included; optimized for both street and demanding track sessions
• TÜV/DOT Homologated Stainless Steel Braided Brake Lines: Included for a firm, consistent pedal and improved brake fluid integrity under heat
• Complete Hardware Kit: Includes mounting brackets, adapters, and all required fasteners for a clean installation

Developed from Brembo's decades of motorsport experience in Formula 1 and endurance racing, the GT Series combines radial-mounted fixed calipers with oversized 2-piece rotors to deliver braking that is noticeably more immediate and consistent — whether navigating daily traffic or repeated high-speed stops on the circuit. The complete bolt-on nature of the kit means everything needed for installation is included in the box.
