I finally settled on installing a Koni/H&R setup on my M Roadster. I occasionally participate in track days, but mostly the car is my summer time DD. My question is - what else should I replace while I'm in there? I was thinking shock mounts and new bump stops. Ball joints, tie rods, motor and tranny mounts look good. Rear subframe reinforcement is definitely on my radar and I'm going to replace the bushings back there at the same time (I don't want to have to disassemble the rear end twice). What else am I missing?

On the front I bought the lower spring rubber and new upper strut mounts. That is pretty much a go to for me every time. I’ve not replaced those bearings before on other cars I’ve had then they start making racket.
To be honest after you take it apart one time you could probably do it again in about two hours so if you forget something it’s not the end of the world.
In the back the rogue rear shock mounts are really nice. I just added a 2nd 7.5mm upper spring pad in the rear a week or two ago. My rear was sitting a little lower than the front, it’s pretty common to do
In the front:
Control arm bushings
Sway bar bushings
Bearings
Rear:
Diff bushing
Sway bar bushing
Bearings
If needed.

In case you don't know this (not from me, but one of the pundits here): If you have no weld issues now, and put in poly subframe bushings, your odds of having weld issues in the future are almost zero.
