Well I do know that static weight distribution is useful from left to right to balance the car, but front to back is subjective. The left and right of the car is mirrored. same shocks, oils, springs, camber locations (assuming no oval, lol). But front to rear has many many variables. based on how you want the car to feel on and off power etc. I would use your scales to balance left to right and not worry about front to rear.
