I just put the racer tech two inch lift kit on with their heavy springs for my sachs shocks. It will raise your rzr-s 2 inches plus, and thats great for going over rocks but will take a little control away from fast hard corners. If I had it to do over I would have gone with the medium springs for a better ride. But I ride trails mostly and go slow and easy.
I have the Racer tech lift and their medium springs on my 09 S.
I did the lift first then about a year later I did the springs.
It is night and day better than the stock setup.
I disconnected the sway bar and it is so much better at rock crawling.
It is not as stable at high speeds (more body roll) but you get used to it.
If you do mostly high speed racing, power slide type of riding you might want to keep the sway bar connected.
I prefer it disconnected.
In my opinion the lift and springs are two of the best bang for your buck mods you can do.
