I am in a similar situation. I'm planning to start with the M3 control arms/torsion links plus rear subframe bushings. I was considering camber plates, but am concerned about NVH issues, as I won't compromise daily driver functionality. Is there an upgrade for the top bushings, without going to camber plates?
I think I'll leave sway bars until I fit an LSD. I like the idea of a square setup for autox - perhaps on 17s.
