Optimum Front/Rear height difference
Can anyone suggest the optimum in height between the front and the back? Should they be the same height from the ground, of should the back be up a little higher? Anyone know?

Ok measuing from the frame( dont use the fenders as they are no were near equal)
There are several places to measure, the A-arm mounting points & frame rails. On the frame rails. just in front of the front jacking puck holes and just behind the rear jacking puck holes.
Over all the car should not be lowered more then 1 1/2" Ideal is 1" ( front measurements)
So when you lower your car measure and adjust the front first.
then the rear
the rear jacking puck holes should be 4-5 mm higher then the front holes.
This will account for the proper aerodynamic rack the car needs.
equal left to right ( with weight of driver in drivers seat - i use 11 old brake rotors at 17 lbs each and 3/4 tank of gas)

Man thats alot of work,I dont think I have 11 old brake rotors laying around,exactly what does the car do if this is not fairly equal,I lowered the front by taking the whole bolt out,I could not turn them as they were frozen on so i cut the bolt with a sawzall and inserted a piece of the rubber bushing as to not have it rub metal to metal,so how far should the front be from the ground to the jacking puck to be ideal, then if this is at the ideal heighth then take the back up 4-5mm higher,what if you like the look higher than that in the rear? would this cause any problems,i am waiting to get my alignment done as I just lowered it recently. thanks

Or let a shop corner weight it for you: http://hotrod.com/howto/113_0309_scale/
I've been putting it off, as I'd like to get that done and alligned right afterward as well. Unfortunately, most regular alignment places I know of are a joke, and I haven't asked around about corner-weighting it while adjusting the ride-height down around an inch.
