I had my hellbents on top of my friends subi and we were goin 130mph on the way to the mtn and we passed my friends car and he said my hellbents were almost bent at a 90 degree angle... then I checked the camber on them and hey! what do you know I got another cm of rocker on the "top" ski in the rack.
so we flipped over my skis and did it again on the way home, then they were equal again. but after that I started to put both skis on the rack "base up" so the skis could have a down draft on the car and not get more fucked up... just something to ponder...
