From what I gathered at various places today, the answer is 'sometimes'. It sounds like they help compensate in certain situations. My guy at the tire place who's going to do the mount/balance said he'll see what they (wheels) look like when they get here. I just ordered some from Lakeshore Wheel and Tire in MI (ebay) for $975 shipped. Jason at LWT said that they don't need hubs, so we'll see. He also told me that each wheel they ship is spun-out previous to delivery. I'm keeping my fingers crossed on this deal!
