2003, base. it had 110k miles and I believe most parts were original except sway bar links and a pair of control arms (front I believe).
Shocks - KONIs red. They give quite comfortable ride, same height, and stiffness in turns. They supposed to be "mechanically active" or something like that.
As for a difference - you know, hard to say. I got the car at 107k miles, drove 1500 miles, where 1000 was from Boston, MA to Lansing, MI, and I cannot really say how it was when it was good... so sorry, no advice on it.

The S version is more tricky due to the fact it may have the "sport" susp.
Word of advice, though. Replace all of them.
If none were ever replaced, you may experience weird behaviour. Especially if you use KONI along with stock on the back.

Hi there, I saw your post on suspension parts. What year is your Boxster? I'm just after replacing my front struts right now and satisfied with just keeping it stock. Are those Konis you have listed for an "S" Boxster? Any noticeable difference in ride? Appreciate you posting that list.
