Clutch Masters 02-21 Subaru WRX/STi .75in Bore Master Cylinder Upgrade Kit - Black

This kit includes a new Clutch Masters 0.75-inch bore master cylinder, finished in black, designed as an upgrade for 2002 through 2021 Subaru WRX and STi models. A properly functioning clutch master cylinder is crucial for transferring the force from your clutch pedal to the clutch slave cylinder, allowing you to disengage the clutch and shift gears smoothly. When your original master cylinder starts to wear out, you might notice a spongy pedal feel, inconsistent engagement, or difficulty shifting, especially when the clutch is hot.

This Clutch Masters upgrade features a 0.75-inch bore size, which is a common choice for enthusiasts looking for a more direct and responsive clutch pedal feel compared to larger factory bores. A smaller bore generally requires slightly more pedal effort but offers a more precise engagement point, making it easier to modulate the clutch during spirited driving or track use. The well-built construction ensures reliable operation, and the black finish gives a clean, updated look to your engine bay. This part is designed to fit right into your existing clutch hydraulic system, simplifying the installation process.

When replacing your clutch master cylinder, it's a good time to inspect your clutch line and slave cylinder for any signs of wear or leaks. Ensure you have fresh, compatible clutch fluid on hand for bleeding the system after installation, as this is critical for proper operation.
