Dunno.
The tow hook is there so that you can get around the angle issue of the long, low bumper; the winch on the tow truck will be higher than the lowest point on the bumper, so the strap/cable will pull up on the bumper if they attach to the suspension.
If they figure out a way to do it without a tow hook or damaging the front fascia, I'd like to know how they did it for future reference.
