I have installed 4 pair of convertible ones and have another set to do on a car. What I can tell you is that the installer can make a big difference on how "pregnant" they appear. I don't have any to measure at present to help.
What you need to do is look inside the wheel housing and see how close the skin is to making contact with the inner rubber seal on the inner wheel housing.
I have not had any experience with 2DR SEDAN quarters to know if this is a problem with those.
