The Brembo 1ND.9531A3 is a front GT Series Big Brake Kit featuring a 405x34mm (15.9") 2-piece slotted rotor and a 6-piston cast monobloc caliper finished in silver. Part of Brembo's acclaimed GT upgrade lineup, this kit is engineered from motorsport-derived components to deliver a significant step up in braking performance, pedal feel, and thermal management over stock systems.

Key Features:

• 6-Piston Cast Monobloc Caliper (Silver) – Radial-mount aluminum caliper machined from a single cast billet for exceptional rigidity and minimized flex under extreme braking loads
• 405x34mm 2-Piece Floating Rotor – Oversized composite disc with aluminum alloy bell reduces unsprung weight and allows radial and axial float to dissipate heat and resist thermal warping
• Slotted Rotor Surface – Precision-machined slots continuously clean the pad surface, evacuate gases and debris, and improve bite consistency lap after lap
• High-Performance Brake Pads – Application-specific friction compound included, tuned for both street and track use
• Stainless Steel Braided Brake Lines – Proprietary Brembo lines by Goodridge; TUV/DOT homologated for improved pedal firmness and fluid response
• CNC Billet Caliper Adapters – Brembo-engineered brackets and all necessary fastener hardware included for a complete installation
• Twin Seal Caliper Design – Restricts dirt and debris from entering the caliper body, protecting internal seals and extending service life
• Brembo Check Compatible – Scan the unique QR code with the Brembo Check app to verify product authenticity

The Brembo GT System is designed and tested for track day enthusiasts and performance drivers who demand superior stopping power in both everyday and high-demand driving conditions. The oversized floating rotor design improves cooling capacity and increases resistance to cracking from thermal shock. The complete, pre-assembled axle set ships ready to install.
