I'm just curious if anyone here would be able to shed some light on a question I have regarding center-caps...

Does anyone know if the stock RX8 centers, are the same size, or smaller than the Mazdaspeed center caps?

I guess this may be more directed at Canadian owners who purchased their RX8 with the "Performance Package" and received both the stock RX8 rims, as well as the Mazdaspeed rims that came on it (That were originally for the MAzda6)

Also, is there a size difference in the center-caps from those particular Mazdaspeed Mazda6 rims and the Mazdaspeed RX8 rim centercaps?

Or even yet, does anyone know of a place to buy blank centercaps?
