I spent some time searching and didn't find exactly what i was looking. Maybe I'm being dense because I'm tired from working on the car all day.

I swapped out in some new cusco zero2 coilovers for my old hks ls. And I'm not understanding how exactly the height adjust for the rear is supposed to work.

There are 2 height adjustment points in the rear - one on the shock body and one on the spring. I have the shock adjusted as low as it would let me go (turning clockwise - to shorten the shock length) - there wasn't far that i could go. I also have the collar turned about 1/2 way down on the spring perch to compress the spring. (I'm using both rubber stoppers on the spring)

This should lower the ride height, correct?

I have a about a 4 finger gap between the tire and the fender.

What am i missing?

 

On coilovers that have full height adjustment like the Cusco's and have the rear springs in the oem location, rear ride height is set exclusively by adjusting the rear spring perch.

You then adjust the rear dampning length to maintain proper piston stroke (also serves to set rear spring preload). One thing you could do is to compare the rear cusco dampner min and max travel to the oem rear shock and reduce it's length by the amount you have dropped the rear vs oem ride height, just a idea kina hard since I'm not under your car now.

Front height is still set by adjusting the dampner length longer or shorter, (keeping spring preload at the lowest possible level to keep the spring in place should the suspenison become unladen).

 

Thanks.

I got the height I wanted, only after removing the top rubber spring mounts. Is it safe to run the suspension without those? The spring collar would be against the frame.

 

It's safe, but you'll have greater impact harshness on poorer pavement condition's. And under certain parking lot moves, you might hear some sounds you don't like.

 

When adjusting height, make sure you disconnect one of your end link connections. This way the sway bar does not interfere and give you a false measurement.
