Brembo 1S5.6003A2 GT Big Brake Kit 4-Piston 326x30mm Front Red Calipers

The Brembo 1S5.6003A2 GT Big Brake Kit delivers track-proven stopping power with a complete front axle upgrade featuring monobloc 4-piston calipers and large-diameter rotors. This system is engineered for enthusiast drivers seeking maximum braking performance for Subaru BRZ, Scion FR-S, and Toyota 86 sports cars.

Key Features:

• Monobloc 4-Piston Calipers: Machined from a single aluminum billet for superior rigidity and consistent pedal feel under extreme conditions
• 326x30mm Slotted Rotors: Large-diameter 1-piece disc design with slotted pattern to evacuate gases and maintain pad bite
• Red Powder-Coated Finish: Distinctive high-temperature red coating resists corrosion while providing aggressive styling behind open wheels
• Direct Bolt-On Installation: Complete system designed for front axle installation on 2013-2016 Scion FR-S, 2013+ Subaru BRZ, and 2017+ Toyota 86
• Increased Thermal Capacity: Larger rotor mass and advanced caliper design provide superior heat dissipation compared to factory brakes

This Brembo GT system includes everything needed for front brake installation: calipers, rotors, high-performance brake pads, stainless steel braided brake lines, and all necessary mounting hardware. The monobloc caliper construction eliminates flex for improved modulation and shorter stopping distances, while the slotted rotor design maintains consistent performance during spirited driving and track use.

• Rotor Diameter: 326mm (12.8 inches)
• Rotor Thickness: 30mm
• Rotor Configuration: 1-piece slotted design
• Caliper Type: Monobloc 4-piston fixed
• Caliper Finish: Red powder coat

Brembo GT brake systems are developed using the same technology and manufacturing processes that supply Formula 1, NASCAR, and top-tier motorsports programs worldwide. This kit requires wheels with adequate spoke clearance to accommodate the larger caliper dimensions.
