Stupid question, but are all the center caps for Honda wheels the same diameter? I have some Integra wheels on my Fit that need new center caps. Of course, the wheels need to be sanded and painted, too, but the center caps are shot. I also assume the center caps can be painted as well.

 

There are different sizes for each application with some overlap.

Take a look at this site to see some examples.
