But if you were to push on the top of the pole 1/4" the spot that is 6' off the ground will only move 1/16" or less.

Basically it has to do with were the lower control arm (LCA) and coil over mounting points are. If the mounting point for the coilover was closer to the mounting point of the LCA, you would get more lift. If it were farther way from the LCA mounting point you would get less lift. All from the same spacer. It basically comes down to leverage, in a way.

Either this helped you, or just confused you even more. But at this time of the morning I can't really think of a better way to describe it. Hopefully someone else will simplify things alittle.

2.5" lift, the spacer is 2" tall
