IMPORTANT - ADAPTER OR SPACER MUST SIT FLUSH AGAINST VEHICLE HUB, AND WHEEL MUST SIT FLUSH AGAINST ADAPTER OR SPACER! If not, vibration or other problems can occur. Drive the vehicle. If no problems (noise, vibration, anything out of the ordinary), drive about 5 miles, then re-torque the lug nuts attaching the spacer or adapter to the hub.
