For stock OEM black wheels, do I simply need the Gorilla 21134bc which are the shorter version of the 21134etbc? I haven't taken a factory lug nut off yet, but I assume either size would work but before I order am hoping for clarification. Thanks!For lug nuts, I recommend Gorilla 21134etbc. These will center the wheels and provide a little extra bite.
Some wheels have a 108mm bore because the center cap mounts from the back and act as a hub-centric ring (like Method MR305).
If the wheel does not have a cap like this, i would recommend the 1mm centering ring.
