My last SRF had a Butler seat and I used Schroth formula belts- the one with the D ring sewn into the lap belts. The anti-Sub belts routed through the D-ring and looped thru the shoulder belt at the cam lock center.

In my new car I am installing a Butler Seat and I am wondering if I should be using the new style Schroth belts where the anti-sub belts hook directly to the cam lock. Also with the new Butler seat I have the 6 point modification where the sub belts bolt to the bottom of the seat. I was thinking that the end fitting on the sub-belt should be sewn in so I am not sitting on the adjusting slide part.

Anyone got experience to help me out on this?

Take a look at the Schroth web site to see the examples

Now on my 3rd set (just installed) and happy with the 2" lap and hybrid HANS shoulder harness. Did need to do some modifications to the seat so that I got the sub belts in the proper location, and used bolt-in fittings on the sub and lap belts, wrap-around on the shoulder harnesses. I shortened the sub belts as much as possible so the adjuster is below the thigh. I posted up a few photos a while back that show a bit more detail on how I mounted the sub-belts and overall installation including seat mods at: http://www.flickr.com/photos/bobsrf/set ... 518897029/
