The shank of the lug nuts fit snugly into the wheel's lughole, resulting in more thread engagement and a better peace of mind.  Another benefit is the wheels are now not only hub-centric, but also lug centric. Using ET lug nuts provides the same amount of wheel securement that a factory OEM wheel/lug nut setup would supply.  Our ET lug nuts are compatible with all of our wheels.
