Someone keeps saying Z4M is lighter than 135i but the difference is only 140 lb. I thought it was more like 300lb or something. I would hardly call that an advantage. My MCS is 2668 lb.... 600 lb lighter than Z4M. That's a big advantage in the corners. That's like carrying 3 pro football players all the time. or two sumo wrestlers. or a small cow. . . .
