The hole furthest from the axle will provide your vehicle with a lower pitch center and less anti squat. This also has the added benefit of reducing the overall pinion angle variation through suspension travel. With the arm installed in the upper hole your pitch center will be raised for quicker weight transfer to the rear tires and optimized launches.
