(IMPORTANT NOTE: NISMO does NOT recommend this product for use with its COPPERMIX or Sports Clutch Kits due to "insufficient stroke volume" which could result in a mis-shift. It is recommended for use with "metal disc type" clutches. That said, we HAVE seen these NISMO slave cylinders successfully used with NISMO clutches, but it is up to the buyer to decide.)
To reduce the pedal load when using a sports clutch on the 240SX, the size of the operating cylinder has been increased from 3/4 inch (19.05mm) to 13/16 inch (20.54mm). This reduces pedal pressure by as much as 14% compared to a standard part. This will also improve half-clutch operating characteristics and provide proper clutch connection positioning.
