Brembo 1ND.9523A3 GT Series Big Brake Kit Drilled - 6-Piston 405mm 2-Piece Silver

The Brembo 1ND.9523A3 is a complete front-axle GT Series Big Brake Kit featuring a 6-Piston Cast Monobloc radial-mounted caliper paired with 405mm x 34mm cross-drilled 2-piece rotors finished with a silver caliper. Engineered for high-performance street and track use, this kit delivers a significant upgrade over OEM braking systems in thermal capacity, fade resistance, and pedal feel.

Key Features:

• 6-Piston Cast Monobloc Calipers — machined from a single piece of cast aluminum for exceptional rigidity and minimized flex under heavy braking loads
• 405mm x 34mm Cross-Drilled 2-Piece Rotors — oversized floating disc design increases braking surface area and thermal dissipation, with drilled holes to evacuate heat, gas, and brake dust for consistent pad bite
• Directionally Vented Disc Design — proprietary venting geometry improves cooling capacity and increases resistance to thermal-shock cracking by over 40% compared to standard rotors
• Reduced Unsprung Weight — aluminum alloy disc hat reduces unsprung mass for improved suspension dynamics and handling response
• Silver Caliper Finish — painted silver with embossed Brembo logo for a clean, performance aesthetic behind the wheel
• Complete Front Axle Kit — ships pre-assembled and includes high-performance brake pads, TÜV/DOT-homologated metal-braided stainless steel brake lines, CNC-machined caliper adapter brackets, and all necessary hardware
• Motorsport-Derived Engineering — technology developed from Brembo's decades of Formula 1, MotoGP, and endurance racing experience

The Brembo GT Series Big Brake Kit is the benchmark upgrade for performance drivers who demand consistent, fade-free stopping power in demanding street or track-day conditions. The complete, pre-assembled kit simplifies installation and ensures every component is engineered to work together as a system.
