Yep, not happy with them either. Took them a couple of go's to get the right springs. Than couldnt find the time to check their work, after the springs had settled in.
You could try the mob over the boarder. They sell ARB. Or the Guys in Hume.
But I was swopping wheels around the other day and notice the rear axle had very little droop in the OME suspention. looked like the shocks are a little short. And I still got the wrong front springs.
