Idk I like my rigs fast. You'll be lookin at around 40k rpm with the 5700. Quite a bit but not too much IMO. You run on a fairly big track? You could always limit it with the esc settings like max throttle or torque control. Punch controll is horrible for racing from my experience but to each his own I guess. I would run the 5700 since you were planning on it anyway and just see how it does. It will definately be fast!
