One full rotation of the Coilover Adjuster is how many inches? thanks.

 

Not enough!

 

with 1 rotation you most likely will not notice any difference in height..from what i noticed on konigs tein flex coilovers, it seems like it would take about 8-10 full turns before you get a inch out of it

 

I need to lower the rear on my tein flex but have never adjusted coilovers. What adjustments did you make when lowering the rear?

From Tein's site:

Full Length Adjustable -

Vehicle ride height and spring pre-load can be adjusted independently. Ride height is adjustable in two ways: a. adjustable shock length, and b. adjustable spring seat.

a. The lower mounting bracket can be adjusted, thus changing the overall length of the shock, and therefore altering the vehicle's ride height. This also allows the user to determine suspension travel and droop.

b. The adjustable spring seat allows for independent adjustment of spring pre-load without affecting vehicle ride height.
