So I picked up some F&F coilovers and I'm not sure what height to set the rear strut at. I know you're supposed to adjust the height by moving the collars on the spring but what height am I supposed to set the strut at? I measured the difference from the stock spring to the coilover spring, which is 2 inches(I want to lower the car 2 inches), so what height do I set the strut at? Do I just set the strut 2 inches shorter than stock?

Picture for reference:

 

By the picture it looks like you have to thread the strut up so that it align with the other hole.

 

Yeah, I know, I just placed it on top, I just don't get what height to set it at(obviously high/low enough to bolt it down)
F&F says, adjust rear shock length according to control "droop" and preload. Not adjusting the rear shock in relation to the spring height can result in the high/low kit(assembly of spring height) coming loose when a wheel is off the ground.

So, I guess I set the strut long enough so that the spring in the bucket won't fall out or has a snug fit. So do I set it at a specific length in relation to the spring height? Would adjusting the f&f strut to match oem strut length be ok?

 

Anybody know the answer to this question? Iono what to set my struts at either :|

 

Adjust those locking rings on the spring. Then adjust the locking ring on the strut (gold rings)

 

adjust how much, how do you know when to stop or what to adjust?
