BMW E46, E9X, F30, F80, E82, E39, and more - Clutch Master Cylinder Kit

Upgrade your BMW clutch hydraulics with the FABbot 7/8" Wilwood Clutch Master Cylinder Kit. Designed for high-performance street cars, track cars, and engine swap applications, this kit improves clutch pedal feel, increases hydraulic volume, and delivers consistent clutch disengagement with demanding aftermarket clutch setups.

Unlike a standard Wilwood master cylinder, every FABbot kit is precision-machined and re-engineered in-house. We completely disassemble each master cylinder, CNC machine it to properly center the push rod with the BMW clutch pedal, then reassemble it using our custom-machined push rod and high-strength steel spherical rod end. The result is optimized pedal geometry, increased strength, and improved long-term reliability.

Our latest design features a one-piece CNC-machined billet master cylinder mount with an integrated spacer, remote reservoir cap, and OEM-size hose barb. This streamlined design reuses the factory BMW reservoir hose for improved routing, a cleaner installation, and fewer components.
