I have the thule roof rack system installed on my 2009 Rogue S....It will not scrape your paint at all, there's clearance under the fit kit.straight from the thule website

Your'll need the Thule fit kit #1587.
I have the thule Aerobar with length 53"
and i'm using the thule rapid traverse 480r foot pack.
I will get some pics of my roof rack...
