the rear wheels dont have any gap because they dont need to turn.....
check the distance from the ground to the side skirts to the ground in the back and see if its the same as up front. if its the same and you add lowering springs to only the front, it will severely alter the center of gravity during braking, leading to dangerously bad handling.
