Agreed. Thus the slippery slope of upgrades
I know at some point I will want the M3 rear subframe bits, just don't want to pay to have the back of my car taken apart again (and again) thus the consideration of just doing it once (again) and adjusting the Konis to a stiffness that I can live with long term. Given that I am currently at 1.5 off full soft at the rear (and mostly OK except for the chassis flex previously discussed), the thought process is that dialing it back to 3/4 or 1 off full soft should be livable even with the M3 bits. Of course would still like to hear your experiences with your upgrades before committing.
