Do you remember Ryane Motorsports? They used to make a set of lowering trailing arms and knuckles that moved the wheel 1.5" up the suspension, thus lowering the vehicle 1.5" without changing the suspension geometry at all.
I foolishly sold my setup and they shortly thereafter went down a different business avenue (I think they make kit cars now). I've often thought of making a set for myself, but have never gotten around to it.
I've been talking with a 22 year old about this and my final conclusion is 2 on the front, little more on the back to balance out the vault from my springs. Washer trick on the back, try to keep the camber from burning the front tires until I can afford a front camber kit and then I'll go to 3 on the front.
