The bars that attach to the b-pillar (back of the windows) are just there to create the proper angle between the harness and the driver (so the angle isn't too steep, which creates crushing stress on the spine in the case of an accident), they are not there to mount the harnesses to. There are some harness trusses, like the ones Brey Krause makes, but they usually mount to the strut towers or other structural parts, and/or are heavily reinforced. It sounds like this bar may be designed for the belts to mount to if it goes all the way down to the front lap belt mounting points, what's the BK part number?? Most people with harness bars attach the shoulder harnesses to the rear seat belt mounting points. But as Eric points out, this increases the length of the belts, and since they are designed to stretch, this isn't ideal because the total stretch will be more.
Most (almost all??) of us started out just using stock seats and the stock 3-point harness, which were designed by the manufacturer to work well together. As you get more experienced you may find that going to a combination of driver/passenger race seats and a roll bar will be a good solution, though it may be best to get into driving a bit first and seeing how far down the slippery slope you will go
When it is time to upgrade, it would be a great idea to post further questions here, there are many knowledgeable people lurking about
Quote:ok! thanks for the info! I will use the stock seats and belts for this year.
I didn't think this bar was considered a guide. I thought this was where you were supposed to attach the should straps. It is like 6 inches away from my shoulders. This would guarantee the alignment of the straps and the drivers/passenger. What you are saying seems logical, I will have to look at some peoples setups as examples.
