I have the lap mounted and the shoulders mounted to my roll bar. My question is, is there any "rule of thumb" when mounting my anti submarine belts? Does it need to mount closer to the seat? More towards my feet? I am assuming that it doesn't matter but just wanted to make sure it wasn't something similar to "not mounting the shoulder straps on the floor for risk of back injury." Maybe a stupid question but better safe than sorry. Also, it is looking like right in the center there is a nice piece of frame convieniently located on the underside so I can't mount them right in the middle. Can I just mount them to one side or the other?
