2017-2021 Honda Civic Type R

Built to dominate both street and track, the 10th-generation Honda Civic Type R pushed boundaries with aggressive styling, advanced aerodynamics, and a potent turbocharged 2.0L engine. While Honda engineered the platform for wide appeal, factory clutch hydraulics include comfort-focused dampening that can dull pedal response. The Clutch Masters Billet Aluminum Clutch Master Cylinder Kit is designed to remove those compromises and deliver the precise engagement serious drivers demand.

This direct plug-and-play system replaces the factory master cylinder with a precision-machined billet aluminum unit featuring a .700" bore for improved hydraulic performance. By eliminating the integrated clutch fluid damper, the kit dramatically sharpens pedal feel, providing clear engagement feedback that helps prevent missed shifts and enhances driver control during spirited or competitive driving.

Compatible with the OEM slave cylinder, the system can be used as-is or paired with additional upgrades. Many enthusiasts choose to remove the factory clutch delay valve inside the slave cylinder for maximum responsiveness. For a fully optimized setup, optional internal hydraulic release bearings can replace the stock slave cylinder entirely, removing internal restrictors and fluid accumulators. Drivers who prefer a smoother, slightly cushioned engagement can add a flow control valve to fine-tune clutch release characteristics without reverting to the overly dampened factory feel.
