Welcome to the forum Paul.
Nice car!
Being new to the Mustang world, did you know the wheels on your car are from the previous iteration to yours which ran from 1994 to 1998?
They are from a GT of that era.
They would be considered an upgrade on a V6, with wider tires.
Something to talk about at your first car show or meet up with others.
You fit right in.
Wheels are very frequent and popular upgrades, or as I call it, investments.
