[Walt Fricke]

The problem with all of these engine mount tow hooks is that the idea is for the tow truck to snatch your half buried car out of the gravel trap expeditiously. The tow truck driver doesn't want to have to dig a tunnel in the gravel to get to it. Some race venues even specify a minimum height off the ground, though PCA does not.

The cheapest rear tow hook for a 911 is the factory one, which can easily be removed when not needed. Of course, if you have removed the stock bumper you can't really use that.
