I ordered my ST and didn't want a front plate nor holes in my bumper, but one is mandatory here in Ontario Canada. I ordered the Sho N Sto front plate bracket. The bracket allows you to mount it with four screws (attached to lower bumper shield. I used 3M tape on mine with the supplied screws. Can easily be removed and re-attached with the pull of a pin.
I've been driving with no plates since June without any issues or tickets.
