Overview

The Clutch Masters MC15020 is a clutch master cylinder designed for 2015+ Subaru WRX/STI models. The kit includes a rubber hose to connect the factory reservoir to the master cylinder.
Show original supplier description
The Clutch Masters MC15020 clutch master cylinder is engineered to enhance the performance and feel of your clutch hydraulic system, especially for aggressive driving. This upgrade replaces the often aging or leaking OEM master cylinder and importantly, eliminates the factory-installed clutch delay valve. This delay valve is a one-way regulator that slows fluid return after clutch release, which can be particularly noticeable during quick shifts and can impede full clutch engagement before acceleration. It is designed as a complete plug-and-play kit and is compatible with OEM slave cylinders. The kit includes everything needed for installation, such as a rubber hose for the reservoir connection. This master cylinder is specifically designed for the 2015-2021 Subaru WRX/STI and the 2022+ Subaru WRX. It is explicitly noted as not compatible with 2002-2014 Subaru WRX/STi models.
