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

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 four-piston cast aluminum calipers, two-piece 345x28mm slotted rotors, and the necessary mounting hardware to get them installed. This kit is designed to replace your factory front brakes with a more robust and capable setup, offering improved stopping power and heat management for spirited driving or track use.

The calipers are a substantial four-piston design, which means more clamping force applied evenly across the larger 345mm rotors. These rotors are a two-piece design, featuring a cast iron friction surface that's slotted to help vent gases and dust away from the pad surface, maintaining consistent braking performance even under heavy load. The cast aluminum caliper bodies are well-built and designed to dissipate heat effectively, reducing the risk of brake fade during prolonged use. The kit comes with all the necessary brackets and hardware to mount these larger components to your Civic Si's front suspension.

When installing a big brake kit like this, it's important to ensure you have adequate clearance within your wheels for the larger calipers and rotors. It's also a good time to consider upgrading your brake fluid to a higher temperature rating to take full advantage of the kit's capabilities. Refer to the manufacturer's installation instructions for specific details on mounting and any required modifications.
