An ABE certificate is available for all CMS wheels. Due to standart offset and wheel sizes close to the OEM series production, the registration requirement dispenses for most applications. Due to European guidelines of the Economic Commission for Europe ECE R124, the European wheel market demands more and more for wheels with ECE standard. ECE wheels are „reversed engineered wheels“ which are based in the technical dimensions of the original wheels which are already registered in the vehicle documents. The wheels are marked with the ECE symbol and the ECE approval number. No documents need to be carried.
