This is a new video from Vossen Wheels, small company based in Miami Florida specializing in design and manufacturing of concave wheels. These 20' VVS-CV3 babies make the IS250 look like a porn star. They manufacture some quality beautiful looking rims, and most importantly they have a 5 year warranty on all of them, I have never heard of something like this before. Obviously these rims are not cheap.
