Meh. I paid the extra money because I wanted something STi.... actually, the car came with it, and I didn't argue. It feels much nicer than stock, that's all I can say, because I haven't played with a Kartboy yet, and probably won't, because I'm not gonna throw out the SS I have just to put in another one
especially if the bushings are the only thing that changes the feeling. As for bushings..... I may try the KB ones.
