4route, you are welcome! I really like companies that innovate the way NE has with the relocator mounts. Very cool. I hope you do well.
gonzo, since you have a Sport Edition, you have XREAS. Since you have XREAS, you're currently stuck with spacer lifts. Since you want 1.5" of lift, I believe Nitrous Enterprises is probably the only choice. You may be able to get one of the Revtek or Daystar lifts and only use part of it.
A lot of people have been running 3" lifts and even a few 4" lifts for quite a while now without the relocator mounts. I have yet to hear of a single problem. So 1.5" of lift should be just fine, I would think.
