Bigfoot,
Remember with 5-points, used correctly & safely, they must be worn 'tight'. No slack in the belts. Basically, you and the seat are 'one'. This is great from safety standpoint, but extremely annoying on the street. Let me explain. How many times driving your Viper do you have to lean forward to get a better view out the side windows, or to check your blind spot? Or reach to grab a CD, etc...? I do these things pretty often, and with 5-points, you can't. Other than your arms, your upper body is welded to the seat. On a race track, there great. On the street, I will stick with the standard belt. Remember, a 5-point belt worn loosely is unsafe, and your better off with the stock belt. My .02 after experiencing both worlds.
