I believe the back spacing is 4 5/8 or 7/8, a SpyderTrac 1.25" wheels spacer was used to set the wheels out a bit. The Wheel spacer can be deleted if you prefers he sucked in look and possibility of rubbing.
Ran into an issue with the front SpyderTrac spacer as it was ordered for my vehicle, I forgot to adjust the part number for a 96-99 Tacoma with Manual Hubs.... Had a machines hope bore the center larger (essentially the same diameter as another Chinese set I had).
