I did modify my air dam to be 6" above grade, but it's still there.
Attach the front edge of the side skirt REALLY well.

The air dam is a little annoying for service, I can't use ramps and it's hard to see the front jacking point. I don't jack it up from the side, but I should check if I can still get the scissor jack in there if I have a flat tire. I'm pretty sure I can with 6" of clearance. So far, the biggest issue is that I keep kicking them. Getting in and out of the car and even just getting something out of the car.
I keep looking at the bulk conveyor belting at Tractor Supply, but the coroplast was free.
