hey guys,just wanted to let pro 4 owners know that my front shock tower is actually the rear tower mounting locations but in the shape of the front tower.i found this to be the best all around location being that it is very adjustable in the right areas and also sits lower so you can lower the front of your body.the spacing between the tower holes and the suspension arm is not changed much.my rear tower is the same as stock,therefore they should fit fine.hope this helps
