Well there are 5 arms in the rear, vs. only two in the front, so it's trickier. The lower camber arm in the rear requires new shocks. Of the two upper arms, I've been told that the Guide Rod Kit is the most effective upgrade. HP Autowerks is still working on the toe kit, so I don't think that's ready yet.
So I'd start with the subframe bushings and rear guide rod kit to start. I may do that in the future when I have some time. It's very labor intensive to replace the subframe bushings in the rear.
