Brembo 1G3.9007A2 Gran Turismo Big Brake Kit with Multi-Piston Calipers

The Brembo 1G3.9007A2 Gran Turismo (GT) Big Brake Kit represents the pinnacle of high-performance braking technology for street and track applications. This comprehensive brake system utilizes oversized calipers and rotors to dramatically increase brake torque and thermal capacity, delivering superior stopping power and fade resistance under extreme conditions.

Two-Piece Rotor Configuration:

The GT system features Brembo's advanced two-piece floating hat and rotor design that reduces unsprung and rotating weight while enhancing heat dissipation. This floating rotor design allows for thermal expansion without warping, ensuring consistent pedal feel and performance during aggressive driving.

Complete Kit Includes:

• Brembo multi-piston calipers (2, 4, 6, or 8 piston depending on application) with sequentially sized pistons for balanced pad wear
• Two-piece floating rotor assemblies available in drilled or slotted configurations, up to 16 inches (405mm) diameter
• DOT/TÜV approved stainless steel braided brake lines for improved pedal response
• High-performance brake pads formulated for aggressive use
• Floating anti-rattle hardware for quiet operation
• Billet aluminum caliper mounting brackets for precise fitment
• Complete hardware and fasteners for seamless installation

One-Piece Rotor Option:

Select applications feature one-piece rotor designs up to 14 inches (355mm) for a cost-effective performance upgrade while maintaining Brembo's quality standards.

Key Features:

• Available in red, black, or silver caliper finish options
• Most applications include TÜV certification for European compliance
• Fully compatible with ABS and traction control systems
• Direct bolt-on installation with vehicle-specific brackets
• Sequentially sized pistons provide optimal pressure distribution

Important: Wheel measurement and brake clearance verification is critical for proper fitment. Ensure your wheels provide adequate clearance for the larger caliper and rotor assembly before installation.
