I really don't know what all the dimensions are when I'm looking at rims for my car. So what is a 40mm offset? And is the 73 bore the center whole? I could use a little help here. Thanks.

And I'd like to know what PCD 4x100/ 114.3

Offset is the distance from the mounting flange of the wheel (flat spot around the bolt holes) to the center line of the rim. It controls how far the tires stick out of, or tuck into the fenders. I'll let someone else explain the others.

all right 4x100 is 4 lugs with 100mm distance from nut to nut. mustangs take 5x 4 1/2" on the 5 lugs. dont really know on the 4 lugs.
