Since it's a triangulated system you've got to think about where the top (front) of the triangle is Donnie. That's basically the fulcrum point that the rear works off of. If you lower the bottom arm it moves the fulcrum point up above the CG point but if you move the lower arms to a parallel with the ground it moves the point to a better position. You still have to do some changes to the uppers to for a better IC but you can get the IC position more towards the center of the chasis for better control of a launch.
