I have a crossmember for my rear links so the clearance is gonna be tight. Since I do have the crossmember there though, it should be easy to build a removable skid plate that protects the disc. Unfortunately the owner sent out an email yesterday saying there's been some issues with some components in the circuit board. He asked everybody to hold off on the wiring until he gets the new boards made. So I can install the hardware but will need to wait a bit to get it all functional.
Here's a screenshot from his video, you can see it doesn't hang down much lower than the tcase itself:
And here is my tcase with the crossmember right behind it:
