any time you make it wider, it will not steer as tight. this kit should be fine if you dont intend to jump. The benifit of arms to the kit would be more wheel travel with longer arms. I may just make my own kit like this... imagine a 57"wide raptor...just wonder how Ill do the brakelines. Id be using this kit primarily for flat track anyway. the added weight would help me too. Since my front end is already gusseted, I am not woried about frame strength. Yeeeee Haaaa!
