Default Changing ride height

I would like to lower my ride height, I have corner weighted my car at the current ride height. My question is if I lower each corner the same amount say 1 or 2 turns on the shocks will the corner weights stay the same? I don't know if the ratio is the same for the front and rear suspension as to how much drop you get with each turn on the shocks.

Theorectically might be possible but due to camber gain, your geometry will not be what it was set at before. And with 993 bump steer what it is, your front toe will be out as well.

I understand I will need to reset the alignment, I have Evo uprights so the bump steer is not so much of a problem.

OK, I see. Each of the settings will affect the other. So, with ride height drop, camber will change -- with camber change, corner weights will change and so on.

I will return the camber to the specs I now have along with the toe, I guess what I am asking is the front and read suspension ratio the same as far as 1 turn on the shocks equals the same amount of drop front and rear. Does 1 turn equal 1/4 inch or 1/2 inch.

On my HR+Bilstein equipped car, I find that changing the rear has roughly twice the change as the front. Can't remember exactly what it was when I tried to measure it, but i think it was around 3mm change for every 2 turns in the front.

This would depend entirely on the motion ratio F vs R -- I dont yet know these ratio's on the 993.
