First ever aftermarket roof rack system I have bought. At first I was overwhelmed with how to install it but I found a video on youtube and it made it a lot easier to understand. The instructions Thule includes are not very detailed and kinda hard to understand in my opinion. Once I got the hang of it it was quite simple. The only pain is the measuring. It was a little difficult to judge the tightening tool which is supposed to tell you when its at the right tension, because I thought I had it right but the Rapid Aero cross bars looked like they were bowed in a little, so I loosened them up a little and they seemed to unbow. Now I can't wait to get my kayak stacker up there and get in the water.
