The Stradman strikes again. This time the Utah super car youtuber reviews these suction cup style ski racks made by Sea Sucker. Judging by their website, Sea Sucker  mostly deals in suction cup boating accessories (rod holders, beverage holders) but their product also seem to work as a minimally invasive ski rack that can easily be swapped from car to car.  They use two 6″ (210lb rated) vacuum cups and provide 24″ of holding space and are sold for $375.
