How strong is this tow hook? OMP tests the strength of their tow hooks by simulating the load of the heaviest FIA GT car being towed out of a gravel trap. The hook is bolted to a rigid test fixture and then subjected to a series of 5 loads of 2400 kg (5280 lb), plus 3 further pulls at a speed of 100 mm / min (4 inches per second). If the hook breaks, it does not pass!
