Brembo 1A4.6004A1 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. Engineered specifically for the 2005-2009 Mazda 3, this complete front brake upgrade features 330x28mm one-piece drilled and vented rotors with black calipers that bolt directly onto your vehicle's original suspension without modification to the brake master cylinder or ABS system.

Complete Kit Includes:

• High-performance fixed aluminum 4-piston calipers in black finish
• 330mm x 28mm one-piece vented brake rotors with drilled surface
• Performance brake pad set
• Stainless steel braided brake lines
• Aircraft-quality mounting brackets and hardware

Key Features:

• Bi-angle chamfered cross-drilled holes reduce stress cracking during high-temperature braking
• Corrosion-resistant rotor coating prevents rust and enhances wheel appearance
• Direct bolt-on installation compatible with stock master cylinder and ABS
• Fixed caliper design provides consistent pedal feel and superior heat dissipation
• Large diameter rotors increase thermal capacity and reduce brake fade

This front axle system significantly upgrades braking performance where it matters most. The Gran Turismo system's fixed aluminum calipers and large-diameter rotors work together to provide shorter stopping distances, improved brake modulation, and enhanced fade resistance during aggressive driving. For optimal fitment, verify wheel clearance before installation as minor modifications to OEM steering components may be required.

Application: 2005-2009 Mazda 3 (Front Axle)
