Brembo 17-20 Civic Si Sedan Front GT BBK 4 Piston Cast 345x28 2pc Rotor Slotted Type1-Yellow

This Brembo GT Big Brake Kit (BBK) for the 2017-2020 Honda Civic Si Sedan includes everything you need to significantly upgrade your front braking system. You get a pair of Brembo's signature yellow 4-piston cast aluminum calipers, two 345x28mm two-piece rotors with a slotted design, and all the necessary hardware to get them installed. This kit is designed to replace your factory front brakes, offering a substantial improvement in stopping power and heat management.

The calipers are constructed from cast aluminum, which keeps them strong yet relatively lightweight. Their 4-piston design allows for more even pad pressure across the rotor surface, leading to better braking performance. The two-piece rotors are a key component here; the 345mm diameter provides a larger braking surface, while the 28mm thickness offers more thermal mass to absorb heat. The slotted design on the rotor faces helps to vent gases and dust away from the pad surface, maintaining consistent grip even during hard braking or repeated stops. This combination is what allows the system to handle the demands of spirited driving and track use without fading.

Installing a big brake kit like this is a significant upgrade, and it's important to ensure you have the right tools and knowledge. While this kit is designed as a direct replacement for the factory front brake components, always refer to the manufacturer's installation instructions for specific details and torque specifications. The improved braking performance will be noticeable, especially when you push your Civic Si. This kit is a solid option for owners looking to enhance their car's performance and safety for track days or aggressive street driving.
