Little help with leaf springs

Mancini.says JRS on them..I'm going to call in a bit..I know it's designed for the launch...but I really don't want my car lop sided even if it is half inch .it is not a drag strip car so don't want it to look like crap or maybe I'm wrong and I won't notice it as bad and it's better for performance obviously... What to do..I know over think it!

if you didn't want the car to sit lopsided why the hell buy springs that make a car sit lopsided? why mix and match springs anyway? there are so many options out there now that fit what you are doing better then what the hell you are doing...
