10.5% grade = 6° angle. (Had to look it up)

Bungie's would be great for the experimental stage of the project. For the long-term I would prefer something a little more resilient than rubber filaments.

I like option B better with a top hinge. A bottom hinge requires armadillo slipping plate armor crossbred with a slinky in order to allowed to articulate and accordion
The bird cage/ skin supporting structure would have to be extremely rigid(read heavy) to survive the torsional load applied to cause it to slide up an example of .A

I was thinking more in terms of MotoGP for the skid points extremely abrasion-resistant bolt on out of the box at this time 2 pucks are $59

With the air dam I experimented with I went beyond what I saw as an acceptable lower limit just to determine how far I could go before I would start hitting the ground 2.5' forward of the contact point of the tires at 10 in of height is where I ran into the ground on the aggressive driveways the normal driveways that don't have chunks of pavement missing from their impact points, 10" was just fine. @8" parking blocks for Troublesome and driveways folded up like a taco shell. Fortunately this prototype was set up for rapid prototyping and it was not difficult to set right after an impact.
