Thanx to all the comments just ordered Kanzen Balls and a set of center Pulleys hopefully there will be an option to get one out of metal. I try to change B4 Spurs. Jimmy you re totally right the rear diff is totally bad after 7 runs I will rebuild it and seal it with some stickers. Hard testing goes on yesterday on dusty slippery clay track and the next sunday on gras hopefully taking the first points to the german championship.
