Barbarian Racing wheel spacers bolts will need to be fitted to the OEM torque settings. These should be shown in the vehicles handbook.
How to tell if a bolt has snapped or sheared:
A snapped bolt will show signs of elongation/necking either side of where the metal has parted. It will also be easy to remove the snapped part from within the female threaded section (the nut). Cut a slot in the snapped section if there is material to do so and it will wind out with a screwdriver.
A sheared bolt will show signs of rotation on the ends of the parted sections. The sheared section will be extremely difficult to remove from within the female threaded section (the nut).”
How To Install Wheel Spacers;
Always make sure you are installing wheel spacers/adapters that are designed for your vehicle. Never use wheel spacers/adapters which do not fit properly. Before jacking up the car use a tape measure to check you will have tyre to arch clearance after the spacers are fitted.
Park your vehicle on a hard, level surface. Break loose, but DO NOT REMOVE, the lug nuts that fasten the wheel to the hub with the tire iron or breaker bar BEFORE raising up your vehicle.
Slide an automotive jack under the vehicle at an appropriate lift point and raise the vehicle enough to lift a single tire completely off the ground. Place a jack stand under your vehicle, and lower your vehicle on to the jack stand. Never work on or under a vehicle which is lifted only with an automotive jack, because it can easily fall or tip, causing injury or death.
Finish removing the lug nuts on the raised tire. Slide the wheel off the hub and set it aside. Spray degreaser on the lug studs and wipe them down with a rag. If the hub is dirty, rusted, or pitted use a wire brush to clean up the surface. Wipe down the entire hub surface, making sure it is clean and smooth.
Wheel to hub clearance check, before doing the final installation on cars with studs pressed into the hub it is essential to check that the wheel will seat on the spacer correctly. To do this fit the spacer/adapter to the hub and torque to specification. Then using a metal ruler/straight edge check that the OE studs do not protrude the face of the spacer. If there is no protrusion move to step 7. If there is protrusion then move to step 6.
It is now VERY IMPORTANT that you check the protruding parts do not touch the wheel. If anything other than the face of the spacer touches the wheel it can lead to the spacer failing, worst case this results in the loss of a wheel. There are various methods that can be used to gain the required clearance.
If you are using Loctite to secure your spacer/adapter, place a drop of loctite on each wheel stud. Place your wheel spacer/adapter on to the hub, with the holes in the spacer lined up with the wheel studs, making sure the wheel spacer seats firmly against the hub. Attach the wheel spacer to your hub using the included bolts. Tighten the nuts that hold the spacer in place to the appropriate torque specification using a torque wrench. Do not overtighten or undertighten the nuts. If you have difficulty tightening the nuts because the hubs turn, have an assistant gently press the brake pedal to prevent the hub from turning.
Now check the hub rotates freely, if you have to release the parking brake ensure the vehicle cannot move by chocking the wheels that are on the floor.
Slide the wheel onto the studs protruding from the wheel spacer/adapter so that it seats firmly against the spacer/adapter. Install your original lug nuts and tighten them to the appropriate torque specification. Tighten bolts in a star pattern to ensure proper seating of the wheel onto the spacer. Raise the vehicle with the automotive jack, remove the jack stand and lower the vehicle onto the newly installed wheel.
Repeat steps 3-9 for each wheel.
