OEM 19" wheel on the E9X M3 are 26 lb R, 23 lb F. The very nice RAC aftermarket wheel are 21/20 lb respectively and are pushing the envelope between weight and durability. In short there absolutely is no way for 10 lb to be saved per wheel without exotic materials or a wheel that won't pass TUV standards.
