Good questions, Pokey. It does have rubber suspension in the undercarriage but as I mentioned, we have no field experience with it. I suspect you are correct about the rough ride. The lugs on the track are not real high though.

You also ask a good question about frame height. We are NOT going to just mount it to our existing hub. It is hard to describe but there is a flange plate at the end of our axle. There will be a very secure mounting with a couple different heights you can bolt to. Not easy but there is height adjustment. We think we can get close based on our field experience with these bars so far. A track will probably not sink in as far as a tire (rolling radius) but on the other hand the tracks will be higher loaded...I am concerned about the same issues you are. We will check out some others experience with these units as Newguy suggests below. Thanks.
