Ya gotta consider arm length, it is a big factor also, most folks run a bigger diameter bar on the right front, than on the left, then you can run heads up on the rear, same size both sides, because of the difference in the arm length, it will make up for it on the RR, or of coil over, same thing in front, stronger spring on RF. Just my 2 cents worth! And DAD is right, no two drivers like the same thing, like I said before, just put a setup on it that'll get you safely around the track, and work from there. Bob!
