Thanks,

what i can tell you though is that i ran my car several times at 2 IHRA tracks and once at an NHRA track before i installed my crotch strap and they never paid attention to it. they always just looks at how the shoulder straps were attached and the date on that. i now use the crotch strap for my own good though
