For many items, the compatible vehicles are listed directly. If not, the item name may provide a clue, or you can contact us and we will check fitment.

What is the delivery time?

Items in stock are shipped within 1-2 business days. Items located at the manufacturer in the USA or Europe arrive within 5-7 business days and are then shipped. All other delivery times are available upon request, as these items are not kept in stock by the manufacturer.

Are there any additional costs?

Within the EU, there are no additional costs such as customs duties or import fees. We import each item to Germany first and then ship it to you from here.

Are the items street legal?

If an explicit indication is missing, the products do not have type approval or ECE. They are not road-legal across the EU without individual approval / inspection. Installation without approval will void your vehicle's registration and may violate local road traffic laws.
