How much Forward offset were you using . Super ATV says their 1" forward offset a arms will not cause that problem . They said they tested them extensivly and no problems . And yes the Rhino 2.0 have greater articulation over stock .I had offset arms on my XP900. It does affect turning radius slightly. The main problem is you will break your cv joints on the axles if you back up while turning sharp. SATV supplies steering stops with their arms but then your turning radius really sucks.
I was running stock axles, and then Highlifter, both had the same issue. If you can find axles that can handle the extra angle you might be ok.
You might talk to SuperATV and see if their Rhino 2.0 will work
