That's true, harnesses should not be used with a stock seat, but I believe Chris has plans to purchase a race seat. The website was simply a reference for mounting points. Many sanctioning bodies prefer a six point harness to protect the pelvis in a severe impact, over a five point.

A couple years back, I attended a safety tech session held at Northstar Motorsports with Dr. John Melvin (reknown safety expert), where he demonstrated the affects of different harness sytems. A six point does a far better job holding the pelvis in place than a five point, due to inherit give in the seat and belt mounting point. Because a five point will always have some flex or angle associated with it's mounting, it may allow the lap belt to move slightly and crush the pelvis.

Now realistically, we're talking DE here, not ALMS or other high speed event. But incidents do occur and people get injured from improperly installed safety devices.

BTW, NASCAR (not that I'm a fan) has mandated a six point belt system since the Ernhardt crash.
