Brembo 1A2.6005A1 GT 4-Piston Front Big Brake Kit 328mm Slotted Rotors

The Brembo Gran Turismo (GT) 4-Piston Big Brake Kit delivers exceptional stopping power for both daily driving and high-performance street and track applications. This complete front brake system is engineered to bolt directly onto your vehicle's original suspension without modification, maintaining full compatibility with the stock brake master cylinder and anti-lock braking system (ABS).

Kit Specifications:

• Configuration: 2.8 4-piston fixed aluminum calipers
• Rotor Size: 328mm x 28mm (12.9" x 1.1")
• Rotor Type: 2-piece vented and slotted design
• Caliper Finish: Black
• Fitment: 1998-2004 Audi A6 front axle

Complete System Includes:

• High-performance fixed aluminum 4-piston brake calipers
• Large diameter 2-piece vented and slotted brake rotors
• Performance brake pads
• Stainless steel braided brake lines
• Aircraft-quality mounting brackets and hardware

Key Features:

• 2-piece rotor construction reduces unsprung weight while improving heat dissipation
• Slotted rotor surface evacuates brake dust and gases for consistent performance
• Rotors feature corrosion-resistant coating to prevent rust and enhance appearance
• Fixed caliper design provides superior rigidity and pedal feel compared to floating calipers
• Significantly larger rotor diameter increases thermal capacity and reduces brake fade
• Engineered specifically for your vehicle's weight and braking requirements

Installation Note: Minor modification to OE components may be required. Wheel clearance measurement is critical for proper fitment—verify your wheels will clear the larger calipers and rotors before installation.

Brembo Gran Turismo systems are designed primarily for front axle replacement where braking demands are highest. For a matched appearance, Brembo Sport slotted or drilled rotors are available separately for the rear axle.
