Then you want the hottest possible motor (extra $$$), pay for the grams in cutting gears and MIP drivetrain, ceramic bearings for efficiency. The entire chassis is specific, then some lighter HV batteries are in order. A grand later and your racing the "spec" class.
Original question stands though; for the minute differences in efficiency, are the spec ESC's really giving an edge vs say the old RS gen 2?
I don't think it's worth the extra money. It may give you slightly more performance but, in reality, spec racing is really about maximizing your corner speed and consistency. One crash or bad lines over the course of a heat will more than offset any gains you may have by having a spec class specific ESC.
