Description: If you look at the clutch master cylinders (CMC) on these cars more closely, you'll notice that all of these models have a triangular shaped feedback plate positioned at the very end of the cylinder. This plate is basically a secondary valve that was designed to slow down the clutch engagement and reduce shock to the clutch itself and the surrounding drivetrain parts. This setup might be perfectly fine for people that just drive their cars for simple daily use, but the delayed engagement can cause wear to the synchros and possibly even the gears on performance applications. the factory CMC delays the clutch operation, so it does not open fast enough to keep up with a fast shift. This means that pressure is being applied to the transmission synchros during the shift, before they are ready for the actual gear change. The Clutch Master Cylinder Upgrade Kit was designed to completely replace the original factory cylinder and offer real time clutch engagement to support faster shifting. We have put together a complete bolt on kit that includes a direct replacement CMC, our high pressure 3AN clutch line, plus all of the necessary fittings needed for installation. The factory clutch fluid reservoir is reused and connected the same way it was in stock form. The only thing we suggest is checking out your slave cylinder on the trans to confirm it is leak free. Aside from that, installation is pretty simple, install the parts and bleed the system using some new clutch fluid. The Slave Cylinder is a great upgrade for those wanting to replace leaking or worn out OEM units. Many new for K-Series cars (for RSX 05-06, for Civic Si 06+) use a slave cylinder that has an internal oil restrictor that further slows the movement of the fluid. Similar to the master cylinders that have a feedback plate that reduces speed of the movement. This can be problematic as reduce speed can cause the clutch to not fully disengage and engage as quickly as you are shifting. This can cause prematurely worn synchros or gears.
