Brembo 2P3.8045A1 Gran Turismo Rear Big Brake Kit - 4 Piston 345mm

The Brembo 2P3.8045A1 Gran Turismo Brake Kit delivers motorsports-derived braking technology for high-performance street and track applications. This complete rear axle brake system features advanced two-piece floating rotor design that reduces unsprung weight while significantly increasing thermal capacity and brake torque compared to factory brake systems.

Kit Includes:

• 4-piston aluminum monoblock calipers with sequentially sized pistons for balanced pad wear (available in black finish)
• Two-piece floating rotor assemblies (345mm x 28mm / 13.6 inches) with hat and disc design for superior heat dissipation
• Type III curved slot rotors that continuously refresh the braking surface and evacuate brake dust and gases
• High-performance brake pads engineered for extreme braking conditions
• DOT/TÜV approved stainless steel braided brake lines
• CNC billet aluminum caliper mounting brackets
• Complete hardware kit for seamless installation

Performance Features:

• Two-piece rotor design reduces rotating mass and allows controlled radial and axial float to prevent thermal distortion
• Cast iron rotors with gold zinc coating provide excellent corrosion resistance
• Aluminum calipers feature differential piston bores to eliminate pad taper and ensure even wear
• Twin seal caliper design prevents debris contamination of brake fluid
• Fully compatible with ABS and traction control systems
• TÜV certification for quality and performance assurance

Important: Wheel clearance verification is required before installation. Most applications require 17-inch or larger wheels to accommodate the larger caliper and rotor assembly. Measure your wheels carefully using proper clearance specifications to ensure proper fitment.
