I have the typical JK 'lean' to the right, so ordered some 3/4" PPm spacers from DBOR. They were out of fronts at the time, but sent me the rears by request. I fitted the one in the right & now the rear seems to sit flat. Just waiting for the fronts to come after Easter. Onya DROR!
Also I backed into a tree...
In my defence, the bugger was growing up to about a meter, then almost horizontal, so I couldn't see it in the mirror. It was just high enough, that the bottom of the spare was where it hit. As a result, I now need a new spare carrier...
On the bright side, as hard as the hit was, the door still opens & closes with no problems.
