If I were you, i'd be getting angry at donkey kicking that produces at my tracks. Bottoming out is okay, But dragging your butt along the track is not.
Stiffer springs or thicker oil is not really a good solution as either has an ill effect on handling. I've already tried both and don't like the feel of the truck. I'd rather not upset the handling of the truck for scraping. Worst case, I'll just replace every 2 months. I could try your ideas about limiting up travel, I was thinking of adding more droop anyways.
I think the only time the chassis is making contact is on the jump face or the transition, more on the face. This is where the truck encounters the most "G" force planting the rear end. As an example, buggies will spark up the face of the jump as they make contact with the "grit".
Symmetricon, I think a skid plate would be good thing for your "sponsor" to try to prototype. One that was the rear pin holder, bumper and a little extra coverage all in one.
I'm sure it would only take a couple of minutes in Solid Works and 10-15 on his CNC Machine
Seriously now, there is not much mounting locations back there so who ever built one would have to be creative.
