Brembo 1N3.9547A1 GT Big Brake Kit 6-Piston Front 405x34mm 2-Piece Rotors Black

The Brembo GT Big Brake Kit 1N3.9547A1 delivers professional-grade braking performance with a complete front axle upgrade featuring massive 405x34mm 2-piece floating rotors and 6-piston monobloc calipers finished in black. This system is engineered to provide substantially improved stopping power, fade resistance, and thermal management compared to factory brakes, making it ideal for high-performance street driving, spirited canyon runs, and track day use.

Key Features:

• 6-piston monobloc aluminum calipers with black powder-coated finish for durability and style
• 405mm (15.9-inch) diameter by 34mm thick 2-piece floating rotors with aluminum hats for reduced unsprung weight
• Type III slotted rotor design for improved wet weather performance and pad degassing
• High-performance brake pads specifically formulated for Brembo GT systems
• Stainless steel braided brake lines for improved pedal feel and response
• All necessary hardware, brackets, and installation components included
• Direct bolt-on installation designed for specific vehicle applications

Brembo's 2-piece rotor design separates the cast iron friction ring from the aluminum center hat, reducing rotating mass while improving heat dissipation. The floating rotor assembly allows for thermal expansion without warping, ensuring consistent performance even under extreme conditions. The monobloc caliper construction provides exceptional rigidity and even pressure distribution across all six pistons for maximum pad contact and stopping force.

This GT system represents Brembo's street-focused big brake kit line, offering race-proven technology in a package designed for daily drivability and long-term reliability. The black caliper finish provides a subtle, sophisticated appearance that complements any wheel design.
