The rear adjustment only gives you about a half-3/4" of adjustment, it is for fine tuning the ride height. You can not make major ride height changes without re-indexing the rear torsion bars.

 

In my experience you can almost get the stock tires to tuck up in the wheelwell. This is for the most part really too low for city driving involving potholes, speed bumps, etc. With a little trial and error you can find the height you want.

 

can someone explain to me in steps or what i have to do to lower it i looked at it and i have no damn clue

 

OK, I am going to assume you don't have access to a lift. In that case raise and support the rear of the car. Remove the rear wheels. As you look at the hub/rotor notice the wide flat bar that goes towards the front of the car (horizontally). Towards the front of this bar, the springplate, you will see two large nuts. Loosen, DO NOT remove, these just enough to allow them to be turned. The nuts, I believe, are 24mm and I think the bolt heads are a 36mm and 27/24mm-can't remember for sure. Before you move the eccentric scribe a mark around the smaller plate so you know where you started at. Be careful when adjusting the eccentric as the bolt head is very shallow and allows the wrench to slip off easily. Try 5-8mm downward (the direction of the small plate in relation to the long one), tighten and see if that's low enough for your taste. I don't know exactly the correlation of how many mm's at the plate to how many inches (or fractions thereof) at the wheel. Good luck and feel free to ask about anything that's not clear.
