Well, for those wondering... I'm at 116,000 miles. Original shocks. So I bought the KYBs (all four) and had them put on today. Not a SHOCKING difference, the old ones were still doing some of their job. But in speedy curves I can feel the car is more stiff, stable and sure. I do feel bumps in the road more, not a LOT more. Verdict: $225 for the set (if you get them from KYB outlet) and $204 labor (included changing the steering stabilizer) - well worth it, as I ready myself to head to CAA6.
