i bought koni yellow struts and shocks 3 yrs ago from tuning zubehor, i was going to install new springs the other day and came to find that both fronts are blown. i was under the impression that konis carry a lifetime warranty, but when i called tz today the guy told me that it's only 1 year! he said he'd contact germany (whatever that means) and get back to me tomorrow. i'm going to be raging pissed if i can't get these struts replaced. can someone confirm for me that konis carry a lifetime warranty? if i can't get these replaced can they be rebuilt?
