I installed a set of 1" spacers on the front to stop tire rub on the frame and upper control arms. On the 2nd Gen GM Twins, 1" spacers require you to cut the oem studs down so they will clear the back of the wheel. It was a simple process and you don't lose any of the threads so it shouldn't be an issue if you ever want to remove the spacers and run without them.
Quick work with an angle grinder and a cutting disk. You can see how far the oem studs protrude beyond the spacer.
After cutting. I just hope the differences in stud length won't throw off balance. I would recommend marking the studs with a sharpie so you can cut them all to the same length.
