The OEM 350Z HR master cylidner is known to fail over time and cause poor clutch release or cause the pedal to drop half way to the floor or stick to the floor completely.

This will cure the pedal drop issue these cars are know for esp when upgrading to a aftermarket clutch and also make the system much easier to bleed due to its higher quality design.

Only mod needed to install is to cut about 1" off the stock reservoir fluid hose.

Professional installation recommended, Proper cltuch pedal/master cylinder rod adjutsment is required after installation. Fits only LHD models.
