Hi Guys,

I am going from 19 Elipsoids to 21" 128's on my 05 645. Do I need anything except spacers? Does it NEED to be lowered or do you just slap em on? If I need a wheel alignment do I do it with the new shoes? And lastly, how do I know they are OEM and not knockoffs. Too late to ask now but it would be good to know. Thanks

Lowering after plus sizing wheels is normally just for looks only. When you lower the sidewall thickness with a lower profile tire the gap between the tire and the fender looks bigger, it's an optical illusion.

You will see "BMW" and a BMW part number cast into the wheels, normally on the back of the wheel, if it's OEM. The Ellipsoids have the number cast on the front under the center cap.
