Brembo 1B3.8028A1 Gran Turismo Big Brake Kit

The Brembo 1B3.8028A1 Gran Turismo (GT) Big Brake Kit delivers race-proven stopping power for high-performance street and track applications. Engineered with Brembo's industry-leading brake technology, this comprehensive upgrade system features larger calipers and rotors that dramatically increase brake torque and thermal capacity compared to stock braking systems.

Two-Piece Rotor Configuration:

The advanced two-piece floating hat and rotor design reduces unsprung and rotating weight while improving heat dissipation. This configuration includes drilled or slotted rotors up to 16 inches (405mm) in diameter, paired with Brembo's multi-piston calipers featuring sequentially sized pistons for balanced brake pressure distribution.

Complete Kit Includes:

• Brembo multi-piston aluminum calipers with choice of red, black, or silver finish
• Two-piece floating rotor assemblies with drilled or slotted design
• DOT/TÜV approved stainless steel braided brake lines
• High-performance brake pads engineered for aggressive stopping
• Floating anti-rattle hardware for quiet operation
• CNC-machined billet aluminum caliper mounting brackets
• Complete installation hardware for seamless integration

One-Piece Rotor Configuration:

For applications requiring one-piece rotors, the system includes drilled or slotted discs up to 14 inches (355mm) paired with 2 or 4-piston calipers. This configuration provides an excellent balance of performance and value.

Most Gran Turismo applications include TÜV certification and are fully compatible with factory ABS and traction control systems. Professional installation is recommended, and proper wheel clearance measurement is essential before purchase to ensure fitment with your existing wheels.
