I got these wheels for free but they didn't have the center caps. I plan on painting them some form of metallic gunmetal at some point. Does anyone know of anyways to get some form of center cap for them? They are Hot Wheels Redline and they dont make them anymore.
Also, in the mean time what can I do to give them a good cleaning. It seems the lip should be a lot more polished than that.

 

Center caps are overrated. loose the locks and get more tuner lugs. Just my $0.02
