designed to cushion people's asses from road vibrations and then fail causing those same asses to possibly end up out of control at the worst possible moment.
Rant on.
The Z's tension rod bushings are a liability issue that I'm surprised have not been linked to someone being killed because of the lack of braking control when they fail. Though this is nothing like the "Energy Suspension" replacement bushings that only cause the lower control arm to crack... it's a shame that in this instance the ES solution was more detrimental that the original problem. Don't get me wrong, the rest of the ES line is great but their tension rod replacements are a huge liability that I wouldn't sell with a ten foot pole.
