I see chrome and silver everywhere, but very few in white. So what is a good source for the white ones?

Or would it be cheaper/less work to buy silver and have them powdercoated/painted white?

 

Yes, it would be cheaper to have them powdercoated. Most of us that have white rims, don't want to get rid of them.

But... if you are interested, I have (4) White 30th Anniversary Rims for sale. You can see them in my sig. Page 3
