The material that our products are made of – ABS – was conceived mainly to be employed in the automotive industry where it is utilized in the production of factory bumpers and other elements of car bodywork, and these items are defined by exceptional durability, and flexibility. The proof of the quality of the parts that we manufacture is the TUV certification that the material has been given, as well as, the fact that a large selection of them is also TUV MATERIALGUTACHTEN/ABE certified.

The creation of tuning components out of ABS is a complex undertaking. The final stage of this procedure consists of manual processing, as well as, applying finishing touches. This clearly shows just how serious we are about achieving the highest possible quality of the items we produce. What’s more, the thorough quality control that all of them are subjected to right before shipping was put into place to make sure that the majority of defective elements can be prevented from being distributed to our customers.
