I could use some advice on Master/Slave cylinder issues...

1slow370 · 06-18-2021, 09:10 PM

I know half of it is unobtainium now but replacing both parts with Tilton pieces fixed all my clutch hydraulic woes. Nowadays the recommended solution is a zspeed cmak kit and new oem master. I'm fortunate I did design work for GTM back in the day and have a Tilton racing master and slave bit you can't get the parts anymore. Does anyone make the aftermarket master cylinder conversion kit anymore?

One other thing you can do. Wrap the clutch hose down by the exhaust with insulation. The heat coming off the exhaust can and will boil the fluid with hard driving. It's one of the things track rats do.

Check with Ryan at RJM Performance. He carries a Tilton HD Clutch Master Cylinder for the 370Z. IMHO the most fail-proof combination is:

1. ZSpeed CMAK
2. ZSpeed insulated clutch line
3. RJM Tilton HD Master Cylinder
4. RJM clutch pedal assembly
5. High quality DOT4 fluid (e.g., Motul RBF 600, ATE TYP 200, Castrol SRF)
6. Bleed the clutch regularly ... at least once per year.
