It can, but mine don't. I have the aero bars from Yak that fit inside the rails and then the aero Thule Echelon mounts on top. Looks great and it's, amazingly enough, quieter than without the bars. No impact on gas mileage.Because fixed roof racks cheapens the look of cars.:thumbsup:
Logged about 7000 miles on my seasucker on my Infiniti, not a scratch.
I just also don't want to deal with the bikes resting on the finish of the car. Given that I drive my Bimmers for 200-300K miles, I am pretty cautious about that.
