I used this to do my Auto to 5speed conversion. I have a JDM VG30DETT and run an ATS twin plate racing clutch and have been running the centric clutch master cylinder along with the centric clutch slave cylinder for nearly 4months now with no issues at all. Definitely a good way to save money! P.S. ~I also recommended this slave to a buddy when his oem slave went out a few months back and he's raced his a few times since and this slave continues to hold up good with no issues.
