Like every season a group of judges discovered points of discussion during the EMMA Sound off events and collected them to create an Addendum to explain the meaning of the rule more detailed and changed some major requests within the Categorization. The main part is the change in the Classification for Experienced and Advanced Classes. Starting from April 1, 2015 all cars in these categories can have modified dashboards without restrictions. This shall open these categories for newcomers and stimulate them to compete. Also the current competitors in higher Categories are allowed to move into the new Advanced except Judges and former national and international Champions. Furthermore a clear description about streaming Media and the ways to use it is described. All further questions about the 2015 Addendum can be discussed in the official EMMA Forum under www.emma-forum.com
