I have a 440ex, I like it alot, but I feel like I need to add to it. What else can I get for it? I want to go faster! I already have everything listed in my siginature... Is there anything else that would just be a good idea? Even if it doesn't improve performance? Please help me out. I really don't want to do suspension till it is blown, (becides, I just replaced it) and I have stock tires and rims off a Z-400
