hey there,
I've been messing with this subject for a few weeks now and have gotten a few very good answers.
If you happen to want to order a set from rs-parts.com (you can brows their site in english) they deliver to the US for 220euro shipping and the adaptors 3 to 5 are included. the tieres are much cheaper here so it kind of makes up for the 220 shipping.
I'm sure smart didn't change the vehicle to where those wheels wouldn't fit.
