as far as i know, those wheels are designed that way. i dont know anywhere off hand (other than your local honda/acura dealer) that sells center caps.

the only place i know of is www.inlinefour.com but the center caps they sell are from a JDM integra type R and are rather pricey.. i'll keep an eye out for ya.

and by the way.. welcome to HAN :wavey: :thumbup:
