Igindoff,
I chose not to use the tow hook mounts in the bumper because I wanted my tie downs centered. In the front, I have a webbing strap that is attached to an inner frame piece directly behind the bumper. The strap feeds out through the grill below the license plate, and the license plate keeps the strap/rope from rubbing on the bumper. When not in use, I remove the tie down rope from the strap, and tuck the strap back in through the lower grill for storage. If you search for threads on A/C condenser protection, you'll find instructions on how to access the space behind the bumper, or if you have small hands you can reach in through the lower grill. Note that I also have a condenser protector mesh installed, but it's attached about 3 inches behind the lower grill, leaving space for my strap. Iif you decide to do something like this, let me know and I can be more specific on exactly what/how I attached the strap to.
In the back, crawl under the car and you can see a steel rail behind the rear bumper. I tied a 5/16" nylon line around that steel rail on both left and right side of the car (middle is blocked by part of bumper cover), forming a loop hanging down just below the bumper. The nylon line is covered with some plastic tubing to keep it stiff. I happened to have red tubing which looks pretty slick. This all sounds complicated, but it took me about 10 minutes to do both the front and rear, and I now have convenient, semi-permanent tie down points.
