I know a couple of owners have posted that they changed the center caps on their rims.
I have the street package 21 inch wheels and just changed to Ford Performance 2 1/8 center caps normally for Mustangs .
Definitely like the new look . I popped the old caps off with a old light bulb suction cup like others suggested . I do not know if I can mention in this post that I got them from a site called American Muscle . I do not know if they offer open box all the time ...but I brought all 4 caps open box for half price .
They sent two still sealed and two open ...my come up .
