Well, my Koni adjustables are shot after +250K miles and my steering wheel is starting to shake when I go over bumps.
When I picked up my car in 2000 it had the H&Rs with maybe 80K miles but was not good as a sole daily driver being that low so I installed 323ti sport springs.
Now that I have another car it's time.
Got a sweat deal on a new set of Konis and will reinstall the race springs on Tuesday. I hope that fixes the shaking problem.
Then off to VIR next month.
