I picked up a '08 dj1 a few weeks back and haven't gotten around to lowering it yet. I need to pick up a spacer to drop it to atleast 80mm or maybe 65mm or so... I'm curious as to if someone may know the I.D./O.D. of the tubing needed and material suggestions. (thought about PVC) Maybe something I can pick up at the hardware store. ?? any help appreciated!
