The rear factory bar can be installed upside down cos I have seen it done. It still worked but rubbed on the chassis/wheelcarrier.
My front one is installed with the curve facing down but that is the way I put it in. I have a 50/50 chance of being right :D :D :D
The rear bar goes with the curve up. The front bar goes with the curve down I think. You have to look at how the ends of the bar look when the car is sitting normally. There is a little bit of twist to the ends of the front bar so you need to look to see that the end links are sitting flat on both sides of that spot.
BTW, I had another comment on my personal favorite position, but we'll just let that be. :D
