Good stock replacement shocks for the rear?

[ChazWhiteZ28-]

Hey guys, lookin for a good stock replacement shock for the rear. i was thinking about the kyb gr2 shocks but most say they are not good or only last about a year before they get harsh. i know the general consensus is bilstein but rockauto has a few cheap options that i would like to get to just have stock like performance. also should i replace the springs at the same time or just do shocks and see how they do?

Thanks- Chaz
