The long length of the VW skinny inertia belts must allow a frightening amount of stretch.

A friend of mine plowed a single seater airplane. He had five point wide belts, and he still implanted his teeth into the instruments- the belts were not fastened very tight, but still stretched more than you would think.

Has anyone installed four point belts with wide webbing? My brother in law has a Humvee and strapped in a small pro racing seat (the aluminum with super high sides) and four point belts for his six year old. You can get a decent seat for ~$200 and that should last until teen years. Kids just love to get into these seats and belting up! and there's no stigma of being in a 'kiddie' booster seat.

I'm considering doing the same for my son.

Any thoughts about is this a good idea or not??? And has anyone improved the stock belts?

couple of sites- look at the cheap $200 seats:
