It does matter on a rack and pinion. Take the left wheel for example.. if a rack is mounted behind the suspension and the rack pushes to the left, the car pushes the left spindle and turns the car right. If it's mounted in front of the suspension and rack pushes left on left spindle, car would turn left.
Funny that you bring this up cuz I have been trying to find something just like this myself. Let me know if you find something.
