i'm with firehead 100% on this one...a arm pivot points are supposed to be as close to center of the "vehicle" as possible, look at the 250r frame thats been used in every form of racing with almost every engine stuffed in it. theres a reason everyone uses that frame...it was the best engineered suspension geometry to date. look where the a arm pivots are. to put that "kit" on something you might ride at any speed over 10mph is stupid...and unsafe at best. not only will bumpsteer be multiplied tenfold, the pressure on the kit itself is enormous when the suspension travels. asr or burgard a arms are the way to go if you want "economical" SAFE wider front end.
i personaly dont think he knows what bump steer is and what causes it.
