While Yakima does list the Q-towers as an option for the 5th gen, I (and a few others) have found that the 3rd gen set up (Q62 clips) to be acceptable in mounting a crossbar over the front doors. It is NOT a perfect fit and the bar has slipped about an inch when driving into 60 mph headwinds at interstate speeds (extreme conditions for many/most drivers). However, the load you plan on carrying may add to the secureness of the bar. By that I mean, if you are carrying a sky box where it is securely fastened to the crossbars, it may help prevent that slippage. The load I was carrying in the conditions above was secured by homemade foam saddles and tiedown straps, so allowed a lot of push/slippage.
In any case I think I'll just get a new ski rack. I found this one and it seems to get good reviews: Inno Grab Max Universal Mount Rooftop Ski...does any one have experience with the Inno racks?
I don't know if this will help you but I just got back from a trip to New Mexico using this for the first time.Thule Universal Flat Top 92725 - Thule. No problems mounted to factory crossbars and I had her up to 85 mph.:naughty::naughty: I had 4 pairs on it.
