I bought an adjustable HANS from the Simpson trailer at the Summer Nationals. After following the directions and mounting the hardware on my helmet, it seems the restraining strap is way too loose. I can bend my head down until the helmet hits my chest. At that point the strap is just out of slack. Does anyone use one of these things? Should you be able to tilt your head that far forward? I don't think the old neck can withstand any real crash testing, LOL.
