Guessing you are saying get the breaker bar (and then torque wrench when putting it back together) on there from underneath the car? Guess I'm ordering new jack stands.
Doing this on a jack is extremely dangerous due to the force you have to apply to loosen and torque the carrier and the rotor itself. Jack stands are the only option and in general the only use for your jack should be to lift the car onto the jack stands.
Yes, the movement of the breaker bar/torque wrench is from under the car, neither will fit from the top side of the wheel well.
