Pretty sure whispbar doesnt have a fit for the Q or nobodys tested it yet. I known Thules 480s work wity fit kit 1551 thats what ive got on there. take a look at my "racked up" thread.Not to bump something old, but I have a Yakima Whispbar system for a car my wife took with her (going through a divorce...). I am searching for the feet replacement, and since Sinecure used the same mounts as the G37, I am giving them a shot later today (if any of the local stores carry fit kit K558) for the feet. If so, I plan to take it out and immediately try it to see if it is functional.
I will update if I find the kit locally, and if so I have a way to haul my bikes and kayak now. Getting excited to have that ability again.
