I spent the morning trying to re-arrange the roof rack to generate less wind noise.
- I had to remove both bars to get the top bar more towards the rear, I presume since the space between the rails shrinks, you can't just adjust one bar while leaving the other installed. I re-installed the rear bar in the correct direction.
- Next I took the front bar off, left only the rear bar in and went for a test drive. The wind noise was definitely reduced but not eliminated. The noise around 40-45 was much better but at 55 it was just as loud as with the front bar forward.
- Next I re-mounted the front bar about half way towards the rear, in the correct direction, then went for a test drive. The wind noise was on par with the test drive with no front bar, much better then the full forward position but still noticeable around 50 mph.
A few conclusion and pointers;
- The powder coating on the RRO side rails and cross bars is not very resilient. Removing and reinstalling the cross bars marked up the side rails.
- Between the marks from install/removal, the requirement to remove the rear bar and the amount of time involved to bolt on an off 16 nuts, it's just not practical to remove the rack while not in use.
- The siderails themselves contribute mostly to the wind noise around 40-45 mph. I suspect they are in the wash from the windshield. If a fairing was to be used, I'd like it to cover the side bars as well.
- Given the bars in there new locations the spread is much smaller then the factory bars which is why I wanted the RRO bars in the first place. The wider the spread the more stable with larger kayaks and canoes.
Cliffs: This kit is for dedicated off road vehicles only. It will be for sale shortly. Given the cost of shipping, and the unavoidable scratches, I will probably take a bath on it.
