How to adjust coilovers?

I’ve got function & Form type 1 coilovers on car. I want to raise the rear a little bit, and in the front the pass side is about 1/2" lower then driver side.

My question is how to raise it. Do you loosen the bottom collar and turn entire set up by hand or how? And then re tighten the collar and it’s good to go? I know not supposed to mess around with 2 top collars as its for the preload.

Thanks in advance!

turn the bottom collar down so it isn’t against the top collar. then raise the top collar to what ever hight you want. and then rais the bottom collar up to where it is tightly against the top collar.
