Brembo 1N1.8521A3 GT Series Front Big Brake Kit 365x29mm 4-Piston Silver

The Brembo 1N1.8521A3 Gran Turismo (GT) Front Big Brake Kit is a complete, race-inspired braking upgrade engineered for drivers who demand superior stopping power and elevated performance on both the street and the track. Featuring 365x29mm 2-piece cross-drilled rotors and 4-piston aluminum fixed calipers finished in silver, this kit delivers the uncompromising braking technology derived directly from Brembo's motorsport heritage.

Key Features:

• 4-Piston Aluminum Fixed Calipers: Radial-mounted with opposed pistons for precise, uniform pad actuation and reduced brake fade
• 365x29mm 2-Piece Floating Rotors: Advanced high-carbon alloy construction with corrosion-resistant plating; 2-piece design reduces unsprung mass and thermal stress
• Cross-Drilled Disc Finish: Precision-drilled rotor surface dissipates heat and evacuates brake dust and gases for consistent bite
• Stainless Steel Braided Brake Lines: Reduces brake fluid absorption for a firmer, more consistent pedal feel
• High-Performance Brake Pads Included: Friction material optimized for this specific application, TÜV/DOT compliant
• Silver Caliper Finish (A3): Bold, sport-inspired appearance with Brembo logo; available in yellow (A5) and other finishes
• Complete Axle Set: Kit includes calipers, rotors, pads, stainless braided hoses, CNC billet caliper adapters, and all necessary mounting hardware
• Street & Track Rated: Engineered for high thermal resistance and precise brake modulation under both daily driving and demanding track day conditions

The Brembo GT Big Brake Kit's fixed caliper design improves system durability and efficiency — opposed pistons act on pads with greater precision, resulting in more uniform friction surface wear and a stable, confidence-inspiring pedal. The oversized floating disc reduces unsprung mass for improved handling dynamics while its exclusive vented vane design boosts cooling capacity and increases resistance to thermal shock cracking. All hardware needed for installation is included, making this a straightforward upgrade over the factory braking system.
