when your on throttle the rotational mass of the armature throws the car’s weight forward onto the front wheels with 3 gear where as 4 Gear turns the motor around so the armature throws the car’s weight back onto the rear wheels so with 3 gear you have more steering but less grip rear end on steering where as with 4 gear you have more rear end grip on throttle but slightly less steering which is over all better as abit of setup change can give you more steering
