I haven't driven my new wildcat in the woods yet so I don't know if the larger turning radius is that much of a problem. There is a kit on the market now for around 5 to 6 hundred dollars where you can transfer parts off the cat 4 (Tighter steering) to the two seaters. There is some talk about it here...http://www.wildcatforums.net/forum/wildcat-general-discussion/4363-wildcat-sharper-steering.html For basically a no cost alternative you can relocate the tie rod by drilling another hole in the steering knuckle. That can be located here. http://www.wildcatforums.net/forum/projects-how/4387-tighter-steering-mod.html
Here is a pic and a video. Several have performed this mod. Advise wait and see what happens.
