Brembo 1B3.8034A3 Gran Turismo Big Brake Kit

The Brembo 1B3.8034A3 Gran Turismo (GT) Big Brake Kit delivers championship-proven braking technology engineered for high-performance street and track applications. By utilizing larger calipers and oversized rotors, this system dramatically increases brake torque and thermal capacity compared to stock brake systems, providing consistent stopping power even under extreme conditions.

Two-Piece Rotor Configuration:

This Gran Turismo kit features Brembo's advanced two-piece floating hat and rotor design, which reduces unsprung and rotating weight while dissipating heat more efficiently than conventional one-piece rotors. The floating rotor design minimizes thermal stress and reduces the risk of warping during aggressive braking.

Complete Kit Includes:

• Brembo multi-piston calipers with sequentially sized pistons (configuration varies by application)
• Two-piece drilled or slotted rotors up to 16 inches (405mm) in diameter
• High-performance brake pads formulated for track and street use
• DOT/TÜV approved stainless steel braided brake lines
• Billet aluminum caliper mounting brackets
• Floating anti-rattle hardware for quiet operation
• All necessary installation hardware for seamless integration

Key Features:

• Fully compatible with ABS and traction control systems
• Most GT applications include TÜV certification
• Caliper color options available (red, black, or silver depending on application)
• Professional-grade construction using Brembo OE specification materials
• Engineered for direct bolt-on installation with included brackets

Important: Proper wheel fitment measurement is critical before installation. Verify wheel clearance to ensure compatibility with the larger caliper and rotor assembly. This brake system requires wheels with adequate spoke clearance and inner barrel dimensions to accommodate the upgraded components.
