I have a set of the Apex EC-7 wheels and I want to replace the plastic center caps with metal one. Can anyone point me in the right direction of anywhere I can find some they they have used. I have looked online and the information I find doesnt seem verified as far as size. Thanks for the help.

Reach out to Apex, they're very responsive and helpful. Last I checked, they were running S550 size wheel cap bores for their Mustang wheel offerings, but that was a while ago so best to verify beforehand. The only source for off-the-shelf metal center caps for S550 wheels I've found are these, but apparently in the notes they're open to doing custom designs (or, I'd assume, blanks).
 
I don't know what year Apex changed the center cap hole size, but I have a set I bought from them several years ago and the hole is larger than a S550 centercap; they won't fit. I bought another set from them a year or two ago and the hole size matches now. Whether yours will fit will depend on how old your Apex wheels are. Regarding metal caps, I have no idea.
 
Keep in mind the Apex plastic ones can melt on track but it is not unusual for the metal caps to pop out. Some groups will not allow center caps on a road course as one flying off at speed can be quite hazardous.
So the plastic ones already melted, lol. So I plan to only put the center caps on when I am not rqcong the mustang.
