New AMV magnesium wheels are the result of years of research and development in magnesium casting. These wheels are casted with the new AMV low pressure machine, using 100% pure AZ91 magnesium. This allows us to assure no air leak, even without any powder coating on the wheel surface. This improves the heat transfer, which is direct and without any obstacles. All this helps to stabilize the tire temperature and pressure rise, for a better and longer tire performance during all race.
