Does the application of leather impact the functionality of individual components, e.g. the airbag?

No. The removal and reinstallation of components is carried out by our certified personnel. This has no impact on the functionality of the components, because the characteristics of the components are not changed.

Is it possible to restore the interior to its original state after the modification?

Not without significant effort. The materials are attached to most components and cannot be removed again. In order to restore the interior to its original state, the individual components will have to be replaced.

Can the leather seam stitching be changed later?

Changing the stitching is only possible for components where the leather is not permanently attached. On seats, for example, the leather, as a rule, is stretched, so that a change of thread would normally be possible here. For the possibilities in a specific case, ask using our contact form contact form.

Can you also install my exhaust system or other exterior components?

Of course we will fit any parts you bought from us to your vehicle. Please ask about the cost of installation using our contact form or the contact details listed there.

Can I just come by spontaneously, or do I always need to make an appointment in advance?

As manufacturers, the individual support of our customers has priority. We prefer appointments as they allow us to provide this support. We will, of course, also provide advice in a spontaneous visit — to the extent that time allows. To avoid waiting, though, please agree a non-binding appointment, so that we can plan sufficient time to answer your questions and address your wishes in a consultation.



Can I come and look at the materials in person?

You certainly can! Our showroom is open for you. For comprehensive advice, please make an appointment in advance. Our personnel will be happy to help you!

How robust are the individual materials, and how can they be cleaned and maintained?

The carbon is given a protective layer of varnish. This has the same characteristics as the paintwork on your vehicle. You can therefore use the same cleaning and care agents.

For Alcantara , we recommend that you only use water and avoid cleaning agents, as these can cause irreparable damabe to the fibres. Wipe the components to be cleaned with a moist (not wet) cloth. Be carefuly not to apply too much pressure to the components.

Cleaning tips are provided without guarantee and are based on our own experience.

Are the materials guaranteed?

The materials we use, along with all other products we sell, naturally come with the legally mandated guarantee. Deliberate damage and incorrect use of the products and components is exempted from this guarantee.
