I've run a couple of configurations and there's a diference. Just sort of depends on what you expect and if you have stock wheels. If you want to get into power slides and flat tracking in the loose stuff, there's a lot of difference especially in right hand turns. If you get in a lot of off camber stuff w/ a 4seat higher cg set up, it helps to feel more confident.
HW is right though.. I'm not sure it's that necessary compared to say a rhino which to me feels much more unstable. With that said, I left mine on
On the front, it can increase the bump steer and you may or may not like them.
If the trails are tight, I wouldn't run them. I can't see how it would help if it's tight already and you can't hang the backend way out.
Either way, you can still roll it! I'm sure it is adding additional stress no matter how you ride. When I run them, it's for safety purposes so I don't worry about the CVs
