These lower-priced engines have quick-change rear axle by a coupler called an "in-out You must do this to prevent making two changes at once, a stagger change and a ride height/weight distribution change. If parallel forward mounted arms are used, there will be an arc created when the axle moves. Winged Designs become "standardized" through trial and error and Sprint Car design is what it is because of the need for simplicity and durability. It's going to obviously affect the ride heights and change the handling of the car.
