Brembo 1B3.8031A2 Gran Turismo Big Brake Kit

The Brembo 1B3.8031A2 Gran Turismo (GT) Big Brake Kit delivers unmatched braking performance for high-performance street and track applications. Utilizing larger calipers and oversized rotors, this system dramatically increases thermal capacity and brake torque for superior stopping power and fade resistance under extreme conditions.

Two-Piece Rotor Configuration:

The flagship two-piece rotor design features a floating hat and rotor assembly that reduces unsprung and rotating weight while dissipating heat more efficiently than conventional one-piece designs. This advanced engineering provides consistent pedal feel and improved handling response.

Kit Includes:

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

One-Piece Rotor Configuration:

For applications requiring a cost-effective solution, Gran Turismo kits with one-piece rotors deliver exceptional performance upgrades with oversized calipers and discs up to 14 inches (355mm). These systems maintain the same Brembo quality and engineering excellence in a more economical package.

All Brembo GT brake systems are fully compatible with ABS and traction control systems. Most applications include TÜV certification. Calipers are available in red, black, or silver finish to complement your vehicle's style.

Important: Proper wheel clearance measurement is critical for fitment. Verify your wheel dimensions before installation to ensure adequate clearance for the larger caliper and rotor assembly.
