You are lucky if you can fit 3 or 4 pairs of skis on this rack. Unless you are using skis from before 1991 you cannot fit 6 pairs of skis on here. On top of that, most pairs of skis are too thick for the mechanism to be shut over your skis and hold them stable on the rack. The bottom rack doesn't even open so good luck wedging a twin tip in there. This rack would have been decent 15 years ago, but now there are much better items. Just get a rack for the top of your car.
