Thanks Red! you answered my question. Sorry it was confusing.Not sure what he is trying to say ......but for cons. A) some people get a wobble like a tire out of balance at certain speeds. kind of strange as most are hubcentric. b) Require checking the lug nuts and the spacer nuts quite often. C) most spacers you cannot torque the lug nuts past about 80ft lbs, wheras JL/JT normally require 130ft lb on the lugs.
