I just got my 19" slipstream silver wheels painted the grey color that Tesla has come out with. Also got the calipers painted the tesla red color. I was struggling over the last few weeks if I should get it done or not as I couldn't really find any pics of the 19" grey slipstream wheels on a model S on the internet. Was going to buy a set of aftermarket wheels but the weather will be changing now so I will hold off. One question I had about after market wheels is if any one knows how does the ride get affected. Is there a big change. I know the profile of the tires will make a difference but just wanted to hear from other people.
