Why havent the chassis gotten wider and longer over the yrs.do they run a rule for that.i know that manufacturers are doing everything they can to maximize speed,but the chassis havent gotten any longer or wider.seems to me they are leaving speed in the fab shop.like a f1 car that thing is long and they are fast or like dirt track guys take a metric chassis and add 4” of width to it.i know that qrc makes their outlaw karts with couple inches of axle travel front to back.but ya dont see it anywhere else.idk just a thought.
