ST165 Coilover options?

you have 2 adjustments. you have a spring perch. then you have a shock assembly adjustment. the spring perch only adjusts the spring. the body adjustment is where you change ride height.

 

you shouldn't need to disconnect anything. just raise the car so the wheel is unloaded. then loosen the jam nut. then grab the shock/spring combo with your hands and apply a little force.
viola! it'll turn. and it won't f' up your camber settings. changing ride height will however affect the toe settings.

if you haven't aligned the car yet than it really doesn't matter.
