The factory clutch line in your RX7 is reinforced rubber. This lineexpands from hydraulic pressure and thus pressure is lost instead of affecting the clutch slave piston. This clutch line is custom made just for the FC RX7, it is not a clutch line that happens to fit.

The Teflon hose is covered with braided stainless steel to resist expansion better than the OEM clutch line. Every CorkSport clutch line comes with a protective coating to keep grease and grime off the stainless braided exterior;

Choose from a clear or black coating. A CorkSport clutch Line is recommended for any aftermarket clutch, but is also a great upgrade for a stock setup.
