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 will say this about spec racing. When you first start out the electronics don't matter as much as your consistency. Once you can get around the track as fast as your car can go and you start to see these "fast" guys pulling on you a little in the straights, that will be the time to think about the better electronics.
If you want to start on a relatively decent budget you can get the Hobbywing Justock ESC and spend the money saved on a nicer motor that you can keep for a long time. The bearings (you can just degrease stock bearings to lessen rolling resistance) and cut gears will just give you tiny edges here and there but these days the motor for spec racing really matters once you get really competitive. The ESC is not so much as the motors don't require a whole lot of amps to move. The better ones may have somewhat smoother throttle response or lower resistance but I don't feel all of that will benefit you as much as getting a good motor to start.
