I'm about to buy an entire set of K badges for my Kia Forte Koup (KIA CERATO KOUP forte koup 2010 Kia Logo EMBLEM SET 7ea: eBay Motors (item 290462311487 end time Nov-06-10 17:15:40 PDT)), however, I have read that the wheel caps are 59mm, not 60mm. Which size is correct? And if it is 59mm, does that mean that the wheel caps are meant to go over the current caps? I thought they were made to completely replace the factory caps. If you have any suggestions towards another buyer/source, feel free to share! Thanks!
