corner balance vs ride height/rake
#31
Drifting
We built some stands for the scales that are a few feet off the ground and we do the balance with the car on a suspension lift. Makes it a lot easier to adjust everything.
If anyone needs a set of the Longacre aluminum ramps to go with the adjustable pads pictured above I have some I never use and would like to sell. I'll take $300 for them, half the price of new ones:

One of the biggest misconceptions about cornerweights is that the weights are completely determined by height, If you turn it around and think of corner weights as pressures it makes it easier to get your head around... And it's the only way to get it really right, nice writeup mike.

but do your ride heights change when corner balancing?

It depends on how stiff the springs are. With cup car stiff springs, it only takes a couple of mm to make quite a change.

The springs are a factor, but the most dominant is the motion ratio, right?
Just thinking out loud. If you are already at equalibrium, does it really matter all that much what the spring ratings are, unless you start twisting the chassis.

At a rest, it still makes just as much difference. If you have a 1500 lb spring, then you will only need to move it 1/3 as far to affect the same weight change as if you had a 500 lb spring. Or to use J Richard's thought process, it will create 3 times the pressure for the same amount of movement.
