I had pedders superlows in my EB.It took about 500kms before they settled properly and they dropped about 2inches below XR6 factory height.I dont know if I got a dodgy pair, but the shocks were dead in under 20,000kms and the springs sagged another 1 1/2 inches over the next 12 months and every bump that I hit bottomed out the front shocks.Ive switched to koni's with lovells springs and the ride is much better.Not quite as low but more fun to drive.Did you leave the bump stops in?I took mine out to give the shocks a bit more travel.
