My rails are on order, but I have a question that I can't seem to answer by looking at available pictures: Is the center section of the top of the roof rails level with the ground, or do they slope up from back to front matching the roof-line of the CX-9? This would matter when installing a roof-top box carrier. If it is going to be tilted up in the air, a shorter box would be better, but if the rails are level, a longer box would be fine. Could someone with rails run out and tell me? I just can't tell from pictures, but I am leaning toward not level, i.e. follows the incline of the roof in that section.
