CSC stands for Concentric Slave Cylinder.
The 03'-06' 350Z used an easy to replace external hydraulic slave cylinder that pushed a clutch fork that in turn pushed the throw out bearing to disengage the clutch disk. The external slaves were nearly bullet proof and if they did fail could be swapped out in about 15 mins.
In 07' Nissan switched the 350Z from an external slave cylinder to an internal concentric slave cylinder which relocated the part to inside the transmission bellhousing where it directly pushes the throw out bearing against the pressure plate release fingers.
Nissan had many failures of this new part in the HR 350Z and recalls/tsb's were issued. Even after a redesign of this part in later models (370Z/G37 included) people are still seeing high failure rates on the oem CSC's which should be replaced any time the transmission is taken out since you need to drop the transmission in order to change out a bad CSC.
