I've been on these things since winter 2010 and they are still doing pretty damn well! Still control the bumps in the road without being bouncy etc. And they aren't overly harsh like KYB AGXs that I had earlier. And keep in mind I live in the rust belt... I had originally bought them to hold me over for 2 years till I figure out something better, but I don't really see a need to do that right now. Wonder how much longer these will last.
