Brembo 1A4.6005A1 GT 4-Piston Front Big Brake Kit 330mm Drilled Rotors

The Brembo Gran Turismo (GT) 4-Piston Big Brake Kit delivers exceptional stopping power for both everyday driving and high-performance street and track applications. This complete front brake upgrade is specifically engineered for 2004 and newer Mazda 6 vehicles and features a 330x28mm one-piece drilled and vented rotor design with a sleek black finish.

Complete Brake System Upgrade:

• High-performance fixed 4-piston aluminum brake calipers
• Large diameter 330mm x 28mm one-piece vented brake rotors with drilled surface
• Performance brake pads optimized for the caliper and rotor combination
• Stainless steel braided brake lines for improved pedal feel
• Aircraft-quality mounting brackets and hardware

Key Features:

• Bolt-on installation designed to work with OEM suspension mounting points
• Fully compatible with stock brake master cylinder and ABS systems
• Cross-drilled holes feature bi-angle chamfering to reduce stress cracking under high-temperature operation
• Rotors treated with corrosion-resistant coating to prevent rust and provide an aggressive appearance
• Significantly increased rotor surface area over stock brakes for improved heat dissipation

This front brake system provides a substantial upgrade over factory brakes, offering reduced brake fade, shorter stopping distances, and improved modulation. Minor modification to OEM components may be required for proper fitment. Note: Wheel clearance measurement is critical—ensure your wheels provide adequate clearance for the larger caliper and rotor assembly before installation.
