I just got my vert rims on my fc (4 - 5 lug, t2 brakes, etc. ) and while discussing the whole thing with my mechanic, he recommended I get some form of centercap for at least the rear wheels so the center of the wheel hub thing isn't exposed to the elements.

I don't like the look of the stock mazda center caps for the BBS wheels, as I think it makes them look smaller than they already are. Additionally, I'm going to ebay them for $20+ a pop. So, painting the part that says Mazda to match the aluminum of the wheels is out of the question.

Are there cheap and "plain" looking centercaps I can get? Or is there a way to fabricate something to just cover that center hub thing (the part that's 3 inches wide at the most)?

Thanks
