Brembo 1J2.9017A3 GT Big Brake Kit 380mm Front 6-Piston Silver Calipers

The Brembo GT Big Brake Kit delivers professional-grade braking performance with a complete front axle upgrade featuring massive 380x34mm two-piece slotted rotors and lightweight aluminum six-piston calipers finished in silver. Engineered for drivers demanding maximum stopping power and fade resistance, this system transforms your vehicle's braking capabilities for aggressive street driving, track days, or towing applications.

Key Features:

• 380mm x 34mm two-piece slotted rotors with floating design for thermal expansion management
• Forged aluminum six-piston monobloc calipers with high-temperature silver finish
• Type A caliper design optimized for front axle applications
• TY1 rotor configuration with directional slotting for improved wet weather performance
• High-performance friction pads included for immediate installation
• Stainless steel braided brake lines for improved pedal feel and response
• Complete hardware kit with all necessary brackets and fasteners
• Direct bolt-on installation with no permanent modifications required

Brembo's two-piece rotor design separates the aluminum hat from the cast iron friction ring, reducing unsprung weight while allowing independent thermal expansion to minimize warping and vibration. The directional slot pattern evacuates gases and debris from the pad contact surface while maintaining consistent rotor temperatures. This GT system was originally engineered for 2007-2013 Chevrolet Silverado and GMC Sierra 1500 trucks (GMT900 platform) but may fit other applications with compatible wheel offsets and clearances.

What's Included:

• Two 380x34mm two-piece slotted front rotors
• Two forged aluminum six-piston calipers (silver finish)
• High-performance brake pads pre-installed in calipers
• Stainless steel braided brake lines
• Caliper mounting brackets and hardware
• Installation instructions

Professional installation is recommended. Minimum 18-inch wheels typically required for proper caliper clearance. This system significantly increases braking performance and requires a proper bedding-in procedure for optimal pad and rotor break-in.
