Thanks, i have heard this once before, but is this supposed to be an obvious lean or nice and subtle. Well i've realized that a majority of the people that notice thier lean do so after lowering so i'm sure that would make it more apparent

 

apparently they are not all completely the same. mine is a half in. different.

 

This subject has been brought up before. I know I responded with something like...what's more important, the stance when you're out of the car or when you're in the driver's seat? Have someone measure the height with a 200 lb. driver in it and see which side is now lop-sided.
I don't know if a lower passenger side stance is by design, I've never heard that one. And as far as I'm aware, spring rates are the same left to right. But, I'll bet if you put the car on 4-wheel scales, it isn't going to be the same left and right.
Also consider what's on the passenger side of the car that adds weight...battery, A/C unit, starter. That's close to 70 lbs. right there.
