It is with great sadness that we must report the passing of another A-Cat legend, known to a great many of us. Matthias Dietz was a beloved and gentle character for many years on both the German and European circuits. His immense knowledge of all things, ranging from the 1970's Le Mans Porsche 917 breaking systems that he worked on as an engineer, up to how he sets his rig up for those light airs, of which he was one of the Kings.
