I see that the OEM 18" wheels have different part numbers for the front and rear wheels. Is there any other difference other than they are marked "front" and "rear"?

 

The rims are exactly the same front and rear. The only thing that is actually different on them when you get the car from the dealership is the tires. The front tires are 225/45/18 and rears are 245/45/18.

There's a peg on the front wheels that prevents the rear rims from being rotated to the front, so I would imagine there's an associated slot in the front rims, which would explain the different part numbers.
