I have the exact same setup. I ordered mine from
www.sportsrack.com and paid less than $200 for the entire package including 4 locks.
I was pleasantly surprised to find the X will still fit in my garage with the Thule rack system on - barely!!
I have noticed some wind noise. I may purchase the fairing available to reduce the noise.
This system is very strong. I have Thule bike carriers and could probably fit 5 bikes up there. I am planning to buy a Thule cargo box that holds 16 cu ft and should be able to put the box and 2-3 bikes on top at the same time. The only catch is I need a 6-8 ft step ladder to get to everything!
