the clutch has been 100% good since I fitted the z22se M32 TTV flywheel.
I have a sprung Helix M32 clutch plate (22 mm shaft and 20 spline / teeth)
I have a F23 clutch pressure plate (basket)
I have a M32 slave cylinder - no spacer required since fitting the TTV flywheel
the z22se TTV M32 flywheel will also fit the z22yh engine
