From about 2 months I upgraded my clutch to South Bend Stage II Daily combo + Silent Disk + ZSpeed CSC + Motul Gear300.
Everything well! The car is most responsive, and the clutch is very usable and "smooth".
Two note:
After 1400Km, I must return to the Stock Nissan Trans Oil (75W85 GL4), the Motul at first was good, but after some Km starting to be "gummy".
In some UK forums, suggests also to buy Moly Slip additive. I bought also this, but the effect (at now) is very impercettible....
Another improvement in changing theTrans Oil was to buy a new Drain Plug with a Magnet.
Dimple Magnetic Oil Drain Plugs. Europes No1 Drain plug supplier.
M18x1.5x12 fit perfectly.
Enjoy
