Wheel Spacers 5x112 66.6 mm Bore 3 to 10 mm Pair

5x112 wheel spacers with 66.6 mm center bore: close the gap between the rim and the wheel arch

This pair of solid-machined wheel spacers pushes each wheel out by 3 to 10 mm, depending on the thickness chosen. A wheel spacer fits between the hub and the rim: it does not change the bolt pattern or the rim's offset, but simply pushes the entire assembly outwards so that the wheel sits flush with the wheel arch instead of being recessed. For small thicknesses, this is the simplest way to achieve a better look.

What a few millimeters of track width can change

• Wheel flush with the arch: the unsightly original gap disappears with just 5 mm on most sedans.
• Wider track: the visual stance is broader, making the car look more planted on its wheels.
• Caliper clearance: 3 to 5 mm is often enough to clear a rim whose spokes barely rub.
• Solid-machined aluminium with an anodized finish, lightweight and resistant to surface corrosion.
• Centering on a 66.6 mm bore on both sides, so that the wheel remains centered by the hub rather than by the bolts.
• Seven thicknesses available, from 3 mm to 10 mm, for precise adjustment.

Safety and regulations: what remains mandatory on public roads

A wheel spacer affects the vehicle's contact with the road and deserves an honest assessment. The only markings on the pictured part are its engraved bolt pattern and a manufacturer's reference; no dated approval markings such as TÜV, ABE, or European acceptance are present. We therefore claim no approval for this item, regardless of what any supplier data sheet may state. Consequently, on public roads in France: the vehicle must remain compliant with its original approval, the wheels must remain covered by the bodywork, and non-approved equipment can lead to a failed technical inspection re-test and be rejected by the insurer in the event of an accident. Three points are non-negotiable: longer bolts or studs to maintain full thread engagement, torque tightening as recommended by the manufacturer, and re-tightening after 100 km. Check with your insurer and inspection center before installation.

Technical specifications

Bolt pattern: 5x112. Center bore: 66.6 mm on both the hub and rim sides. Thicknesses: 3, 5, 6, 7, 8, 9 and 10 mm. Material: solid-machined aluminium, anodized finish. Quantity: 2 pieces, i.e., one axle. Type: flat hub-centric spacer, without protruding studs. Fasteners: not supplied. Condition: 100% new.

Installation and maintenance

Allow one hour per axle, with a jack, jack stands, and a torque wrench. Clean the hub mounting surface down to bare metal: a single speck of rust under the spacer will cause it to sit slightly off-center. Install the spacer, fit the wheel using extended bolts equal in length to the thickness chosen, then tighten in a star pattern to the manufacturer's torque. Lower the car back to the ground, re-check the torque, then check the tightness after 100 km and every time the tires are rotated. Finally, check for rubbing at full steering lock and under suspension compression.

Frequently asked questions

Do I need longer bolts with wheel spacers?
Yes, always. The added length must exactly compensate for the thickness to maintain the original bolt engagement depth.

How do I find my bolt pattern and center bore?
The bolt pattern is determined by the number of holes and the diameter of the circle they form; the center bore is the diameter of the wheel's center hole, which can be measured with a caliper.

Which vehicles use 5x112 with a 66.6 mm center bore?
This combination is found notably on recent Mercedes models and G-series BMWs. Be sure to check your own measurements, as the same bolt pattern exists with different center bores.

How many spacers do I need to order?
One pair covers one axle. Allow two pairs for all four wheels.

Are these spacers road-approved?
No. No dated approval markings appear on the part, so we claim none.

Choose the thickness down to the millimeter, get the extended bolts and a torque wrench: that is the only way wheel spacers remain a pleasure rather than a risk.
