Rear Leaf Springs

Ok, here's my stupid question...who in the hell wants their car to sit higher or lower on one side or the other?? I have got no where with MP so I am stuck with springs I can't and won't use on my car. So I guess someone here is gonna get a hell of a deal on a set of MP XHD springs......any takers????
I believe when you buy a set of SS or XHD springs from MP the right side spring is built to set that side slightly higher. The reasoning behind that is torque. Don't know if that answers your question , but I've never seen an even set of MP SS or XHD springs.
