Brembo 17-20 Civic Si Sedan Front GT BBK 4 Piston Cast 345x28 2pc Rotor Slotted Type3- Fluo. Yellow

The 345x28mm two-piece rotor design in this Brembo GT Big Brake Kit is a key feature, separating the rotor from the caliper mounting hat. This design helps manage heat more effectively, reducing the risk of rotor warping under heavy braking. This kit is specifically built for the 2017-2020 Honda Civic Si Sedan, offering a significant upgrade over the factory braking system.

This kit includes four-piston cast aluminum calipers finished in a striking fluorescent yellow. These calipers are designed to provide more clamping force than stock, working in conjunction with the slotted Type 3 rotors. The slots on the rotor surface help to sweep away dust and gas, maintaining consistent contact between the pad and rotor for improved stopping power, especially during repeated hard stops. The two-piece rotor construction also allows for lighter weight and easier rotor replacement down the line.

When installing a big brake kit like this, it's important to ensure you have adequate clearance for the larger calipers and rotors within your wheels. You may also need to consider upgrading your master cylinder or brake fluid to take full advantage of the increased stopping potential. This kit is a substantial upgrade for drivers looking to improve their Civic Si's track performance or overall braking feel.
