Brembo 19+ Mazda3 Front GT BBK 4 Piston Cast 345x28 2pc Rotor Slotted Type-1- Yellow

This Brembo GT Big Brake Kit includes everything you need to significantly upgrade the front braking system on your 2019 and newer Mazda3. You get a pair of robust 4-piston aluminum calipers finished in a striking yellow, two-piece 345x28mm slotted cast iron rotors, and all the necessary hardware to get them installed. This kit is designed to replace your factory front brakes with a much more capable setup, offering improved stopping power and heat management.

The calipers are cast aluminum, which helps keep unsprung weight down while providing a solid foundation for the pistons. Those four pistons work together to apply more even pressure across the larger brake pads, leading to better clamping force and more consistent pedal feel, especially under heavy braking. The two-piece rotor design features a cast iron friction surface bolted to an aluminum hat. This construction helps reduce weight and allows for better heat dissipation, as the hat can shed heat more effectively than a solid iron rotor. The Type-1 slotted design on the rotors helps to sweep away dust and gas that can build up between the pad and rotor surface, maintaining optimal friction and preventing glazing.

Installing a big brake kit like this is a substantial upgrade, and it's often done by owners looking to get the most out of their vehicle's performance, whether on the street or the track. You'll notice a significant difference in how the car feels when you brake hard, with less fade and a more confident pedal. Because this kit uses larger components, it's important to ensure it will clear your specific wheels; check the included wheel clearance diagram from Brembo to confirm fitment with your chosen wheel and tire setup. This kit is a direct replacement for the factory front brake components, but it does require careful installation to ensure proper function and safety.
