My thoughts are that the metalcloak gets rid of all the extra metal hanging down where the flare mounts to, as well as most of the material where the turn signal mounts. The bottom of the MC fender/tube is about level with where the top of the fender was, so you could probably improve the stock fender by removing the flare and trimming the flange. There is also more clearance at the rear towards the firewall, as the MC inner fender meets the firewall pretty much at the bottom corner.
I can see where you wouldn't necessarily get as much additional clearance if you run stock wheels and still had the tire getting up into the area where the hood latches mount and the hood lays down.
