The description on those colorful fold-down hooks linked above says they're rated for 1.5 tons, which is less than your car weighs unless you're in a very stripped out race-only machine. Usually you want parts like that to be over-rated, not under-rated. The stock tow hook from the trunk works fine, and if you want it to be prettier and more visible when you install it at the track (because leaving a tow-hook in on the street is asking for more damage in minor rear-end collisions...), dip it in red Plastidip from a local hardware store
