I'm about to start the process of removing AHC based on the information from various posts here. I went with Ironman Foam Core shocks and springs and OME torsion bars. Can I add a 15mm or 30mm spacer to the rear, will it create too much rake? Currently, I've got BIOR HC rear bumper and tire carrier, BIOR skids, and BIOR sliders for weight. I plan on adding in rear drawers and roof rack as well as front bumper and winch. With this in mind, will the spacer help in keeping the lift high due to the weight? Thoughts?
