Moving springs back 1 "

Currently I have a piece of 1/2" aluminum installed behind the stock replacement mount. I did this to help center the tire in the wheel well. 255/60/15 MT Drag Radials. The studs are still long enough to give more than a full nut.
I also built a set of custom front mounts out of 3/16"s plate to allow me to move the springs back 1". I don't have them installed yet.
