i have the scorpion wheel spacers from 4x4ag. i'm still on the fence on them. i run the 34x10.5 ltb on the disco spare steelie. i love the wider stance i get and i know the wheels are tough as hell. i have only driven on the spacers maybe a total of 30 miles so far. i was told the spacers would need a retighten after an initial run in, but after maybe 20 miles of driving i was retightening. haven't had to retighten since then, but considering you have to pull the wheel off to do it, really not a big fan of that. also, they of course move the wheel out along the hub, so now i can't undo the hub bolts and remove an axle with the wheels on the ground because a socket won't fit around the bolts with the wheel in place. not a terrible thing, but a slight inconvenience that was a nice benefit to the open flange steel wheels.
