Little help with leaf springs

Did you get S/S springs?

(If so, that’s the way there designed to be used no matter who says what. The factory engineers designed them that way.)

Purchased From who?
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!
