the koni yellow shock has an adjustable spring pearch, correct?

I've heard you can make like a 1/2" inch adjustment in your ride height... is this adjustment up or down? I have too much ride hight in the rear when compared to the front and want to drop it a little bit more without buying new springs.... if I get the koni yellows in the rear, can I put it on the lowest spring pearch and make it a bit lower then normal, or is there only a "NORMAL" and "HIGHER THEN NORMAL" setting?

 

I have the koni yellows for my car, and the highest setting in the front is lower than where the stock shock puts it. As for the rear, I'm pretty sure you can go lower than the stock shock allows... higher? I'm not sure.. i forget.

 

basically my front tires are slightly tucked but I still have a noticable gap in the rear... does anyone know for sure? btw my current rear shocks are tokico sports, so I am really just looking for comparisons between the koni and tokico spring perch....
