Brembo 1B3.8047A3 Gran Turismo Big Brake Kit

The Brembo 1B3.8047A3 Gran Turismo (GT) Big Brake Kit delivers unmatched braking performance through advanced engineering and racing-proven technology. Designed for high-performance street and track applications, this comprehensive brake upgrade system provides substantially increased thermal capacity and brake torque through larger calipers and oversized disc rotors.

Two-Piece Rotor Configuration:

Premium two-piece floating hat and rotor assemblies reduce unsprung and rotating weight while enhancing heat dissipation. Available with drilled or slotted discs up to 16 inches (405mm) in diameter, these rotors deliver consistent performance under extreme conditions.

Key Features:

• High-performance multi-piston calipers (2, 4, 6, or 8 pistons depending on application) with sequentially sized pistons for balanced pad wear and optimized pressure distribution
• Caliper finish options in red, black, or silver to complement any wheel design
• Two-piece floating disc assemblies with aluminum hats for reduced weight and improved cooling
• DOT and TÜV approved stainless steel braided brake lines for consistent pedal feel
• Premium high-performance brake pads engineered specifically for the system
• Floating anti-rattle hardware for quiet operation
• Precision-machined billet aluminum caliper mounting brackets
• TÜV certification included with most applications
• Fully compatible with ABS and traction control systems
• Complete hardware kit included for seamless installation

One-Piece Rotor Configuration:

Also available in cost-effective one-piece rotor systems featuring oversized calipers and discs for enhanced brake torque and thermal capacity. One-piece configurations include 2 or 4 piston calipers with drilled or slotted discs up to 14 inches (355mm), along with the same premium brake lines, pads, mounting hardware, and compatibility features as two-piece systems.

Important: Proper wheel measurement is critical for fitment verification. This kit requires adequate wheel clearance for the larger caliper and rotor assembly. All necessary mounting hardware is included for professional installation.
