Back in the old days people sometimes put curb feelers on their car down low near the tires to make a sound to let them know when they were near the curb when parking. I see them for sale on eBay and Amazon, but is there such a thing for an air dam? I have run into parking lot tire stops and not just with the Z. Maybe a curb feeler could be modified to work with an air dam? I imagine it would have to be at an angle so it doesn't get jammed straight back and cause damage to the air dam. Any ideas appreciated.
