Installation

Loosen the Lug Nuts

Common mistake: the first step should be loosening the lug nuts rather than jacking up the vehicle. That’s because you cannot get enough torque on a wheel suspended in the air. So make sure loosening all the wheel lug nuts in turn with a spanner before jacking up the vehicle.

Notification: Just Loosen them, there is no need to unscrew them completely.

• Jack up the Vehicle, Remove the Wheels
• 
  Jack up and support the vehicle on the Jack stand, then remove the jack. Finally, remove all nuts and take away the wheels.
• Clean up the Hub
  Clean gunk wire brush, put some Loctite on the hub and thread pitch. Avoid  collision to the main part and install the wheel spacers to the vehicle.

Installing the Wheel Spacers
Install the wheel spacers, but use the supplied lug nuts instead of the stock lug nuts. Place the wheel spacer on the studs of the hub. Make sure the studs of wheel spacers face outwards. Later, install the supplied lug nut in a star sequence.

Notification:

• Fix thelugnuts in a diagonal/star pattern in sequence. This will ensure a reliable installation.
• Do notuse Impact Wrench during installation! It may cause damage to both the vehicle and the product!
• Please check the exact torque from theinstructions,
• To prevent loose, thread adhesive can be added during installation.

Check the Installation
Failure to clean up may cause a gap between the wheel spacer and the hub, which may allow a vibration of vehicle while driving.

Place the spacer on the factory hub. The spacer should sit flush with the brake rotor. If there is any gap between the brake rotor and the spacer, even if it is small.  Don’t use the spacer! Please be sure to check this. You shouldn’t even be able to slide a piece of paper the spacer on the factory hub.

Reinstalling the Wheels
Install the wheels to the wheel spacers. Please note that the wheel lug nuts should be fitted in the same way as the wheel spacers lug nuts ---- tighten the lug nuts in diagonal or star sequence.

Again it is not necessary to fully fit the nuts in place for this step, just keep them for the next step.

Notification: Fix in the order in which the pentagrams are drawn. In the case of six or more holes, fix them roughly in diagonal order.

Follow-up Inspection
Once everything is in place, drive the vehicle and check for any unusual vibration.
Re-torque all lug nuts after 50-100 miles of driving ,then again after 2000-3000 miles.
