I took my car out to willow last year and there was no inspection of my vehicle. They do require a helmet but that was it as far as anbody seemed to be concerned. Had to have belts and unlike the drag strip keep your windows rolled down. I am sure Steve will see this post and give you a bit more info as he runs that track quite a bit. As said I did it last year and well worth the money to run as long as you want all day long. Make sure your brakes and tires are up to snuff, or your day will be cut short.
