any time there is thrust of any kind whether it be a front, rear or awd car you will have weight transfer the point of the wheelie bars is make sure the front end doesn't lift during a launch. Any matter in motion has this problem. all dirvelines with substantial power, a hard launch will cause the front end of the car to lift because the gravity holding the car down is less than the force propelling it forward. (fast fwd need wheelie bars like any fast car)
