If you are unsure, I would consult the manufacture of the devices.

That being said, I would guess, guess they should go in front of the trailing edge that you are trying to minimize airflow seperation over. The distance in front of that edge & the spacing, I would assume to the the same as on a regular car.

Hope they work for you.
