How to Narrow an 8 3/4 Rear End

That works fine if your wheels have the correct offset. If they don't have the right offset they won't sit where you want. I'm narrowing mine 1" to pull the wheels in where I'd like them to sit. When using the larger brakes it brings the wheels out 3/8" on each side, thus another reason you may have to narrow the rearend

Exactly, my offset on my wheel's wouldn't give me enough room with spring relocation only, my 225 were damn near rubbing already, so this was the best option, and as far as I'm concerned they should have been tubbed this way from the factory. Wheel and tire clearence is allway's a problem on these thing's!
