So the bar would stay as kind of a tube door? A bar door? I dunno what they would call it.
Not sure...
I mean, kinda cool in that you would get a tube door built in. But doesn't look like you can pull that remaining tube part out, so for those people that want to be totally open, no bueno...
One trick I've found that might help you find rattles - either taping things down or cramming rags in-between things (I use cheap microfiber cloths)
It won't necessarily fix anything, but I admit I've got a few spots where I just leave microfiber stuffed in place.
This is pretty much what mine does as well.
I never calibrated mine either - I should, but ... not that important really. I know the computer lies, and I know what MPG I get on average (also about the same ~15.5 as @userdude). But good to know the ability to fix it is there if I were so...
