Did you see the video Nate? If you haven't, let me know, I can send it to you. I don't know how or if I can post on here. The first time out with the 340 it had the stock seat and a lap belt. Wore it on the first pass. But then I started wondering if I really wanted to be strapped to it if something should happen. Needless to say,I didn't use the belts till I installed the cage and seat. What happened to the 340 that night was a combination of things. It was so late at night (12:00pm) dew settled on the track and the driver hit the brakes to hard, tried to slow down way to fast at the top end so he wouldn't break out. I also run Jr dragster slicks on the rear. But I'm not really convinced that street tire would have had any more bite than the slick. Traveling at that speed and dew on the track don't think tires would have made a difference.
