Hybrid Racing Clutch Master Cylinder Spacers

The S2000 clutch master cylinder is great for many reasons—but is certainly a worthwhile upgrade to those with a 1992-2000 Honda© Civic or 1994-20001 Acura© Integra. The OEM CMC for those cars uses a remotely mounted reservoir which can fade and leak over time. Eventually, the OEM line that connects them will fail, which results in corrosive fluid spills and a car that can't move. The S2000 CMC solves that problem by mounting the reservoir directly onto the master cylinder. Clean up your engine bay and enjoy more reliable, better-feeling gear changes at the same time. In order to use the CMC in the EG/EK/DC2, you'll need to run a spacer that corrects the rod and clevis length discrepancy. Hybrid Racing CMC spacers have been tested in race cars for months—and also include a very nice foam seal that will keep water and debris from getting into your cabin. Hybrid Racing suggests using either HYB-CLI-01-02 (if using K20Z1/Z3 slave cylinder) or HYB-CLI-01-08 (if using the K20A/A2/A3 slave cylinder.) If you do not have a K-Series engine, you can still use this part but may need to find a clutch line that works. Spacer notes: * Machined from billet aluminum * Three-stage Dust Black finish * Includes foam seal * Use the S2000 CMC with no modification * Fits both LHD and RHD cars -- 1992-20000 Honda© Civic -- 1993-97 Honda© Del Sol -- 1994-2001 Acura© Integra

Wilwood Residual Pressure Valves

Ideal for drag racing, street rods, and many off-road applications, inline residual pressure valves from Wilwood retain a minimum brake line pressure to help eliminate excessive pedal travel. These 2 lb. valves are used in disc brake applications where the master cylinder is mounted below the horizontal plane of the calipers--in other words, where fluid drainback occurs, causing excessive brake drag. With drum brakes, 10 lb. valves are used to compensate for return spring tension in the drums. Wilwood residual pressure valves are made from billet aluminum and color-coded for easy identification.
