I hate the prices that you have to pay for aftermarket wheel caps. When I bought my Advan wheels I spent like $30 each for the caps and it took about a month to get. I installed them and the first time I drove it I drove 5 miles to work 2 of them were gone. The Tenzo wheels that I had just powder coated had an odd 2.5" hole and most Honda ones are bigger. Again Tenzo wanted stupid money for theirs and nobody has them anyway. Poking around Home Depot I found these knock-out plugs for electrical use, 2 inch was what the package said but they were 2.5 inches in actuality. I grabbed 4 @ $1.20 each, primed and painted them black and stuck them on the car. I've ordered 2 inch round emblems that I'll stick on the new "center caps".
