I'm not sure on much other than the lug pattern and offset working. I actually don't know about NON-center lock or therefore center lock. I am pretty sure I'll be grabbing a set of Advanti Storms though. Now that Dpro made me aware of them that is. When I order I'll have to ask about rings. Other than the fact I know hubcentric rings are required for most wheels, I haven't learned how to find identify the size required for vehicle/wheel on my own.
Center lock wheels use a large single nut to attach the wheel to a single threaded cylinder on the hub instead of studs and lug nuts (or threaded bolts in the case of some older VDubs).
It is mostly used for full-on road race cars, and a very few European manufacturers send them from the factory that way on their 'street legal race car' models (i.e.; some of the upper Porsche GT-xx models, some prancing horsey models, etc.).
For those wheels pictured above those could be just covers over the center lug nut portion of the wheel, which OZed and
many others do for 'aesthetic' reasons, or they could be
actual center lock wheels which OZed DOES make.
What made me think it was the latter is that the center portion of that wheel looks too small to house even a smaller PCD/bolt pattern, but not a single center lock nut.
