Grip is not caused by which way the motor is turning but by the torque reaction that is created by the motor, which is Infact the opposite direction to the motor spinning! In a 4 gear mid motor car the torque reaction spins in the direction of the rear of the car forcing the weight to push down over the rear wheels creating rear end grip. This is why a 4 gear gearbox was created. As when the original x6 with a 3 gear gearbox struggled with grip over the rear on acceleration due to the torque reaction of the motor wanting to lift the rear end causing it to go light!! This is the reason the extra idler gear was added to reverse the torque reaction
