i am looking for a 2.25" round emblem/decal to use for a wheel center on an aftermarket wheel. have you seen anything?

 

I think the dealer actually sells the MINI emblems alone for the
center caps if I can remember correctly.

Try a search too cause I think I read that somewhere...

 

get your local sticker shop to make you some that would cover the aftermarket center cap.. I placed a mini sticker over my aftermarket wheel logo... everyone ask me where i got those factory wheels.... So only you will know the difference... i can email you a picture if you wouldlike...

 

You could use this to make your sticker.

 

Here's a link to my solution for a 60mm center cap

 

The Mini decal in the center of the wheels is available from the dealer.
P/N: 36-13-6-758-687 -- $1.88

And here is a good thread on making a completely custom center cap:
