Torque steer in a front drive car is caused by halfshafts of different length and the flexing in all the mounts moving the wheels to a new location to or from the steeing rack afecting toe.
In a solid axle (live axle) RWD the torque from the ring and pinion is fed through the axle planting one tire and lifting on the other.
Neither of these apply to the TC3 as the shafts are equal and the ring and pinion is on the chassis. I am not understanding exactly what the car is doing that is being called torque steer?
The motor is spinning one way and the shaft with both pinions is spinning the oppisite, those two gyroscopic forces should come close to canceling each other out.
