It was somewhere around 2009/2010 at the latest,probably not earlier than 2009 I can't recall precisely. I can probably make a better call on that if I log on to ozgemini where I got the springs from, as I chased that up not long afterwards.

If anyone cares I got em from a place in melbourne near the moonee ponds/ascot vale tram depot on mt alexander road. they used to be fantastic in the late 80s/early 90s. I've had other bad experiences there more recently (and that time with a friend's early 70s ford, of which surely there's been enough development that they'd have it all worked out, but the first set raised the car 2 inches, then the next set lowered it to near the ground. I'm wondering if they are sitting on old stock or something?

Maybe the ones I got were old stock/earlier design? Hell maybe they changed them after I contacted the qld head office about it (unlikely but who knows).
