Hi, I have a 2003 LS with standard suspension.  I replaced my rear shocks with Bilstein B6s which should be the standard oem replacement vs the B8s which are for lowered springs.  After installing the rears the ride height is almost two inches higher.  Has anyone had experience with B6s?  The part # on the stock shocks I’m replacing along with the door tag and a basic build sheet from Mazda all confirm that I have the standard suspension. 

Thanks, Bill
