So though I hear rumors of 19" turbine wheels being offered soon by Tesla as a factory build alternative, they still disclaim and my car is now in production. So...looking through the great comments on this site and others, I have located two possible after market solutions: Rial offered through Tunershop and Wolfrace offered on their own site both have Lugano (Turbine) style allow wheels. They appear almost exactly alike, and so my guess is they may both be from same manufacturer (sorry uncertain). Therefore price including shipping and tax may be my ultimate guide as to which to order. My questions involve concerns regarding what to do once I get them, and are there any additional items I need to get to make sure they fit the Tesla S correctly. I thought a wheel was a wheel, but as I read more, I'm hearing that perhaps the Wolfrace needs a "centering ring and 3mm offset"... No comments found re the Rial, but if these are really one and the same manufactured wheel, I'm in a quandry as to which is best. Also to complicate the issue, I live in the United States, and it appears the Wolfrace is much more prevalent in Europe, while Rial through Tunershop is easier to obtain here in the US. Is there someone out there that can bring clarity amidst all this myriad choice and confusion???
