Ok, WTF is up with all this alluminum on HPI Micro cars used for racing. Is adding the weight of an alluminum Upper arms, lower arms, rims, bodyposts, alluminum steering slider, front pully really neccesary?? Knuckles are iffy but why a huge ass 1/10 scale touring car shock on the back of micros?? The chassis itself is a spring! Isn't the point of a racer to have a low power to weight ratio? I don't understand this!
