Brembo 1A4.6004A3 GT Piston Big Brake Kit Drilled - 4 330x28mm Front

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. Engineered specifically for the 2005-2009 Mazda 3, this front brake upgrade features 330x28mm 1-piece drilled rotors with silver calipers that bolt directly to your vehicle's original suspension with no permanent modifications required.

Complete Brake System Includes:

• 4-piston fixed aluminum brake calipers with silver finish
• 330x28mm 1-piece vented brake rotors with drilled surface
• High-performance brake pads designed for GT calipers
• Stainless steel braided brake lines for improved pedal feel
• Aircraft-quality mounting brackets and hardware

Key Features:

• Fully compatible with stock brake master cylinder and ABS system
• Bi-angle chamfered cross-drilled holes reduce stress cracking during high-temperature use
• Corrosion-resistant rotor coating eliminates rust and provides aggressive appearance
• Direct bolt-on installation to OEM suspension mounting points
• Significantly increased thermal capacity over stock brakes

Installation Note: Requires minor modification to the OEM steering components. Wheel clearance measurement is critical before purchase to ensure proper fitment with your specific wheels.

Brembo Gran Turismo systems are engineered to handle the demanding thermal loads of repeated hard braking on track days while maintaining smooth, linear performance during everyday commuting. The larger rotor diameter and multi-piston caliper design provide superior heat dissipation and more consistent brake modulation compared to factory single-piston systems.
