A sump impact guard would be the way to go if you are seriously concerned this make have been caused however on previous gravel road Useage.
Indeed... the car in question did go to North Cape. Some really rough surfaced roads there.
I have the photos from the trip and surprisingly the roads don't look too bad, although I think one of the cars suffered a broken light from a thrown stone.
