I was told by a mechanic from snowmobile rental shop that sleds with extra brace have damage to tunnel more often. Sled are design to come apart at a-arms so that that is only damage. Put brace on and you could end up with a bulge in side of tunnel. Its like new car that fold up in the front when they get hit. it take most of impact to save rest of car.
I'd brace anyways to make sure the spindle goes and not the module.This ^^ even the new skidoo spindle is designed to fail first now no sense bracing
