The Z is know to have serious issues w/ the CSC and/or CMC.
Nissan released a service bulletin in 2013 because drivers were having their clutches fail and/or clutch pedal going to the floor and not returning top is normal position.
Per Nissan: Subject: SB 370Z Coupe And Roadster; Clutch Pedal Does Not Return To Rest Position
Summary of NTB13026: IF YOU CONFIRM: The clutch pedal on an applied vehicle does not return to its normal (rested) position after being depressed to the floor OR The customer states the clutch pedal on an applied vehicle does not return to its normal (rested) position after being depressed to the floor *AND There are no leaks in the clutch hydraulic system*. ACTION: Change the clutch hydraulic system fluid with GT-R R35 Special Brake Fluid (see PARTS INFORMATION). - Refer to SERVICE PROCEDURE for bleeding procedure. See this bulletin for further detail.
There's several threads here on the forum about this.
The oem Z fluid fails at high temps, so the quick fix was to replace w/ GTR fluid which is more heat tolerant. This fix often only works temporarily and the CSC and/or CMC still often fail and must be replaced.
