Cragar Lug Nut Help

I read some reviews on using the offset washer on wheels like mine, not a unilug but limited space between the lug and center of wheel.

They commented that when removing the nuts the washer would dig into the side of the rim, and because the washer is concave to act like a lock washer, it sticks to the nut, because it's not off of it yet, preventing removal of the lug nuts.

Great. Looks like it's make your own washer, but you can't because that would be offset, but you need the concave washer so it locks the nut on, but it's too big, so you have to grind one side down, but then it's offset and not fully concave, blah blah blah blah blah blah blah.
