Brembo 19+ Mazda3 Front GTS BBK 4 Piston Cast 345x28 2pc Rotor Slotted Type-3-Black HA

This is the Brembo 19+ Mazda3 Front GTS Big Brake Kit, designed specifically for the 2019 and newer Mazda3. This kit replaces your factory front brake components with a significantly larger and more robust setup, featuring 4-piston calipers and 345x28mm two-piece rotors. It's built to handle the demands of spirited driving and track use, offering improved stopping power and heat management over the stock system.

The calipers in this kit are cast iron, chosen for their strength and ability to withstand high temperatures. They house four pistons, which apply more even pressure to the brake pads, leading to more consistent and powerful braking. The rotors are a two-piece design, meaning the hat and the friction ring are separate. This construction helps reduce weight and allows for better thermal management, as heat can dissipate more effectively. The friction rings are slotted with Brembo's Type-3 pattern, which helps to clear away brake dust and gases, maintaining optimal pad contact and preventing fade during hard braking. The black finish on the calipers adds a clean, performance-oriented look to your Mazda3.

Installing a big brake kit like this is a substantial upgrade for your Mazda3's braking system. It's important to ensure you have the correct tools and follow the manufacturer's installation instructions carefully, as this is a more involved job than a standard brake pad or rotor replacement. This kit is a solid option if you're looking to significantly enhance your vehicle's braking performance for track days, autocross, or simply want the confidence of stronger stopping power on the street.
