JK above is correct. Ackermann is important. Without Ackermann, it will push out when trying to turn. ALL new vehicles from ALL auto manufactures have ackermann. If they didn't their vehicles would eat tires and turn like crap.
Scootercat is also right in that your spindles are setup for front steer. Rear steer, like yours, should have the tie rod to spindle bracket at an angle approx equal to the center of the rear axle.
