FAQ

Yes, wheel spacers and adapters must be registered! However, for most of our spacers part certificates are available. With this, an entry in the vehicle registration document is no longer necessary. You can download the parts certificates on our website at the respective vehicle.



An acceptance test is then possible at TÜV, DEKRA, KÜS or other organizations.

All special spacers and adaption wheel spacers are generally delivered with a certificate according to §21 StVZO and a manufacturer's approval. Here a registration at the TÜV (West Germany) or at the DEKRA (East Germany) by individual acceptance is required.



For vehicles where no parts certificate is available, strength certificates are provided. In the strength certificate the wheel spacers of our various systems are tested up to a thickness of 60mm by TÜV.



If you still have questions or doubts, feel free to contact us.
 

The parts certificates, which are available for the respective vehicle, provide a good indication of which spacer thicknesses are suitable for your vehicle. However, it is unfortunately not possible to make a reliable statement on the basis of the vehicle type alone.

Only after a detailed examination of the vehicle (e.g. by deflection of the vehicle) a statement about the suitable thickness of the wheel spacers is possible. It must be considered that the wheels have sufficient clearance after attaching the spacers. Also the wheel cover must be sufficiently ensured after StVO.

A big problem is also that the tire width can vary greatly with the same size. So if you are not sure which spacer thickness is suitable, please contact one of our dealers, who can then tell you the maximum wheel spacer thickness after inspecting the vehicle.
 

Yes, such a pitch circle adaptation is possible.

We have three different options for this in our range.
 

• System 4L
  - The pitch circle must be the same for system 4L, only the number of holes may change.
  - e.g. 100/4 to 100/5 ; 130/4 to 130/5
  - Minimum spacer thickness: 20mm

   

• System 4M
  - The pitch circles must be very different from each other
  - e.g. 98/4 to 130/5 ; 100/4 to 139,7/5
  - minimum spacer thickness: 20mm

   

• System X
  - For adaptations where neither System 4L nor System 4M works, we have developed System X
  - Here two spacers are firmly screwed together
  - Minimum spacer thickness (total): 25mm

The adaptation of a vehicle with 4-hole mounting to wheels with 5-hole mounting is feasible from a technical point of view, but not permitted from a legal point of view. This means that adaptation spacers with hole number reduction do not receive TÜV approval.
 

System 2 wheel spacers have a double-sided centering. On the one hand, the hub of the spacer must fit into the hub hole of the rim so that the spacer lies flat on the rim and, on the other hand, the wheel hub of the vehicle must be able to be inserted into the wheel spacer so that the spacer lies flat on the vehicle. It is very important that the spacer lies flat on both sides, otherwise the centering hub may break off. As it is possible that the holding capacity of the spacer is not sufficient to lie flat on vehicles with a long wheel hub, we have developed special versions which, with otherwise identical dimensions, have a larger holding capacity due to an extended chamfer on the upper side of the spacer.

The special wheel spacers have an additional suffix after the regular part number.

Explanation based on the spacer with article number 12124/65:
The wheel spacer has a hub hole depth of 15 mm (the regular version 12124: 12 mm).
-  The rim-side phase of the spacer has a length of 6.5 mm (12124: 4 mm). It is therefore necessary to check that the rim has a phase at least 6.5 mm long
-  If the length of your wheel hub is 15 mm or less and your rim has a phase of at least 6.5 mm, you can mount the spacer 12124/65 without any problems.
 

We offer our spacers and wheel bolts in many different coatings.

-  We offer spacers on the one hand uncoated, which means glossy silver and on the other hand anodized. For the second, you can choose between gray and black anodized coating.
-  Wheel bolts and nuts we offer chrome plated, galvanized (black and silver), with Geomet coating and with Dacromet coating.
 

Returns of goods as well as complaints are handled via our RMA module.

Attention please!
Please use the functions "upload pictures" and "add comment" for complaints to make the processing easier for us and to shorten your waiting time. Thank you very much!
 

1. There you can access your orders via different reference numbers (invoice number, delivery bill number or order numbers from the online store).
2. There is the possibility to return the selected order completely or only single parts from it.
3. A shipping label will be created automatically. You can decide whether this label is prepaid (DHL, chargeable) or freight collect.
4. Afterwards a RMA processing number and all necessary documents will be sent to your e-mail address.
5. Now only the RMA overview has to be put into the package and the shipping label has to be attached to the package, then the package can be shipped.
