I'll buy that the 3" race belts are better than the factory 2" belts. Though I highly doubt the factory attachment systems that are tested over and over, built with crush zones are not as good. But that's all a moot point. Why do the threads and material go bad in racecar belts from exposure while pass car belts don't? Do you think if they failed after 2 years of exposure the National Highway Traffic Safety administration would allow the auto company's to build cars with them??????????????? Can you say recall? Maybe the rule will stay, maybe not. What happened when the NHRA was going to require window nets to be replaced every 2 years, same materials, thread and exposure. It was rescinded. Apparently the fact that nets are in the window causes them to last longer,LOL. The rule is wrong plain and simple.
