I joined some 300ZX brethren yesterday at the Mt Cotton skidpan (Brisbane)and had a great day. Of course, it took ages to get the 370 clean again.
Some interesting observations. First is that with the VDC engaged, its literally impossible to get out of shape. It didn't matter how slippery the skidpan was, I could not get the 370 sideways. The other thing is that even with it switched off, it's still active to some degree. I still had to work hard at times to get oversteer and understeer was always managed. Previously, I could come into a corner and the understeer would just take me straight ahead. In the 370, I could feel the traction control working on the front wheels and the Z always came round the corner.
Anyway, here's a quick video:
