Lance, I have replaced mine 3 times now front and rear. The first sets (92-94?)were not up to ***** and Koni redesigned them. I went thru a set and then another and just in the last year my third. But,mu theory is I put them at full firmness for mu autocrosses and then would leave them that way for a couple years. The rears were so hard to get at and adjust. I now will absolutely not even go to 1/2 firmness unless autocrossing. I also spend about a half hour and take out rear seat,shoulder belt,speakers. While I'm at it I see how my sub woofers are doing and I clean up the speakers. Usually find some loose change,m&m's,popcorn under seat. I also find it is beneficial to spray some wd-40 on top of the adjusting stem to prevent it from locking into a set position making future adjustments very hard. I also know that if the rear sway bar bushings are the least bit worn (especially the thicker ones)then this can cause quite a jackhammer effect and cause premature life of the rear struts. And they are lifetime so even if they have to be changed I don't mind because I get the chance to change out the other related parts. I personally have Koni's on all my vehicles since 1984 and will never change that. It'll be interesting to see how long this set last. boink
