Ever remove an engine, transmission, or even slave cylinder from your Miata? If so, you'll know how much of a pain in the rear end it is dealing with the very stubborn factory coiled hard line assembly that goes from the soft rubber hose on the firewall connection to the slave cylinder is.
The way the clutch lines are designed on a Miata leave a lot to be improved. A hard line goes from the clutch master cylinder to the passenger side firewall where it then converts to a flexible rubber line. The rubber line goes for about 10 inches then converts back to a solid hard line that does a loop and then into the slave cylinder. Our full length clutch line is far superior to the factory setup because it connects at the firewall and runs all the way to the slave cylinder, allowing you to remove and eliminate the flexible rubber hose AND the solid line loop going into the slave cylinder.
Our Extended clutch line is longer than OEM rubber hose, and is designed to replace the OEM rubber hose, and along with that also replaces the coiled hard line bolted to the transmission. It does NOT replace the hard line from the master cylinder!
