These locks did not fit my Ford F150 with factory 20" rims very well. The washers cause the locknut to protrude more than the rest, and the flat side of the washer is where the beveled side of the nut would normally fit into the rim. Don't use a washer and the locknut won't grip nearly as tight as the OEM nut because the Gorilla locknut isn't as wide; hence the need for the puck. I believe the solution would be easy if the puck were beveled on both sides. I've tried to illustrate this with a drawing, sorry for my drawing skills. I gave it three stars anyway because I know they are universal and will fit many other cars. Oh, and they don't have metal trim, the closest thing to the rest is chrome.
