I finally got around to removing mine and can confirm it looks much better/cleaner/faster than before. The crossbar is also a heavy bit; so the less weight the better.
Taking the cross bar out was easy; the clips were a pain. I put towels on everything to cut down on the risk of a slip and scratch, and had to wrestle with them a bit until they both snapped off. They would not open wide enough to take off for me without snapping first. Luckily the bars are not scratch prone; once they were off, i wiped everything down and it's all 100%, no damage or scratches to anything.
