Anybody have these or would it void my right to own a mustang if I put a set on??

 

I wouldn't put them on, but that's just me. I bought a set back when I had the 300M, installed them, hated how cheap it made the car look, took them off and threw them away.
You can probably find pictures of a Mustang with them though, see if you like how it looks and take it from there.

 

I have them on if you would like to check it out. The things is my Stang is black....

 

I will post the picture tomorrow since I am adding Cervini window louvers and quaters with a Lengend Chin spolier

 

Yes ...Please post a pic
