I have never seen L40s with innie caps, even the brochure shows them pointing out.
Anyway, you will probably never be able to get those center caps on your mids to pop out, I have tried more than once. They are made of soft aluminum, painted black. Once somebody touches it it gets an annoying little dimple. Then someone gets the bright idea to push it all in, thinking that it will look better. It doesn't. I think that you can buy new caps though.
