Hey guys, I have two questions regarding my wheels.

1. I want to buy new red mini center caps, is there a place to buy high quality ones that match my wheel? I don’t know my center caps size. My wheel is 225/45/17 and by trial and error I know the caps are larger than 56mm. Is measuring with a ruler the best way?

2. Is there a way to restore my faded rim black color? I have used a sonax cleaner which makes it look great for as long as it is wet but doesn’t actually keep it that way.

Thanks!
