Looking to getting my 18" BBS RX's refinsihed, paint is starting to chip and there is curbrash on one of the rims. They are just silver (facotry paint), I was thinking of possibly changing the color, any ideas? It's for a Black 02 325I. Also, either someone stole my two center caps or they flew off taking a fast corner I need some replacements, I have looked around but cant find a solid place to buy them for these rims. Thanks
