I have driven a evo with c-hubs and one without. The c-hubs do help ( at least on a high bite carpet track) The difference is in un-sprung weight. The car with the standard suspension feels very lazy in and out of the corners. Yes it did handle well but just felt lazy. The car with the c-hubs was great. You could throw it in a corner and it would jump out. If I were to race on a high bite track with a evo 2 I would have to get the c-hub conversion. From what I have been told the stock setup works great on the asphault wich makes sense to me. Most of the world seems to race on anything other than carpet so that is most likely why the car comes with the pivot ball suspension. If you have the option of trying the c-hubs give it a try I am not bull sh-ting you it makes a difference.
