Brembo 3K3.9079AZ GT Big Brake Kit Anodized Caliper Upgrade Kit

The Brembo 3K3.9079AZ is a GT Series Big Brake Kit from Brembo, the globally recognized leader in high-performance braking systems. Engineered for drivers who demand superior stopping power, fade resistance, and pedal feel beyond what factory brakes can deliver, this kit represents a significant upgrade over OEM braking components.

Brembo GT Big Brake Kits are built around Brembo's iconic multi-piston fixed calipers, precision-machined from high-strength aluminum and finished in an anodized coating (AZ) for enhanced corrosion resistance and a clean, lasting appearance. The kit pairs these calipers with Brembo's slotted or cross-drilled iron rotors, designed to dissipate heat rapidly and resist warping under repeated hard braking.

Key Features:

• Brembo GT Series fixed multi-piston aluminum caliper(s) with anodized finish
• High-carbon, directional iron rotor(s) for superior thermal management
• Anodized caliper body resists corrosion and maintains appearance under track and street conditions
• Direct-bolt-on design using application-specific brackets — no cutting or welding required
• Compatible with Brembo high-performance brake pads for optimized system performance
• Engineered to meet strict dimensional tolerances for consistent, fade-resistant braking
• Includes all necessary hardware, brake lines (where applicable), and installation hardware

Brembo GT Big Brake Kits are a preferred choice for performance street driving, autocross, and track day use. Each kit is designed as a complete, ready-to-install system, making the upgrade straightforward for experienced installers. For best results, pair with Brembo or equivalent high-performance brake fluid and brake pads suited to your intended driving application.
