You'll find TeamTech's the most frequently used on Viper's. Any belt system that is SFI safety approved should be suitable. Just make sure you get lap belts that pull up to tighten. A sternum strap (built into the TeamTech's) is a good idea too.
My own test of TeamTech's consisted of an end over end with multiple rolls at over 130 mph (in the passenger seat thank you
) and they held up as expected, without a problem. The only thing I don't like so much about them is the large pad areas they have, but that's just personal preference. Once you're out on the track, you have other things to think about and don't notice it that much. Parts Rack and other vendors here carry them. I have Schroth belts in my personal car.
