I just installed coilovers on my Z4MC and lowered the rears too low. Almost 1.5 inch drop. I know it's too low because now the rear wheels have visible negative camber.

How much drop is too much on the rears? How do you guys decide your ride height in general? Stick with stock for best performance, or is slightly lowered better? How much lower?

How do alignment shops do the alignment for rear wheels? I read different things about it online. Some say it's only adjusted by the spring height. I've seen mention of an eccentric bushing.

Also, how do you guys make sure your front/rear ride heights are balanced, i.e not too much drop on one vs the other.

Also, will the alignment shop adjust my ride height and shift the front struts around to fix camber? Idk what these shops actually do beside put the car on a machine and attach the sensors to the wheels.

Thanks for the help.
