Brembo 1A4.6004A2 GT 4 Piston Big Brake Kit 330mm Front Drilled Red

The Brembo Gran Turismo (GT) 4-piston brake system delivers exceptional stopping power for both daily driving and high-performance street and track applications. This complete front brake upgrade kit is engineered as a direct bolt-on replacement for 2005-2009 Mazda 3 models, featuring a 330x28mm 1-piece drilled rotor design with red powder-coated aluminum calipers.

Complete System Includes:

• High-performance fixed aluminum 4-piston brake calipers with red finish
• Large diameter 330mm x 28mm 1-piece vented and cross-drilled brake rotors
• High-friction performance brake pads
• Stainless steel braided brake lines for improved pedal feel
• Aircraft-quality mounting brackets and hardware

Key Features:

• Direct bolt-on installation to OEM suspension mounting points
• Fully compatible with factory 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 enhance appearance
• Significant upgrade in brake torque and heat dissipation over stock components

Installation Note: May require minor modification to OEM steering components. Proper wheel fitment verification is critical—measure wheel inner barrel clearance before installation to ensure adequate clearance for the larger caliper and rotor assembly.

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