Another ad with proceeds going to my Z4 fund... Genuine BMW M badged "Club Sport" 5spd gear knob in near new condition. Shorter length and more weighted makes for a much more positive gear change. See picture 2 for difference in height. Don't have scales to weigh it, but it's at least twice the weight of the standard chrome one next to it. Purchased 31/05/2011 direct from BMW - PN 22.214.171.1246.031 Retail at £46.99, yours for £30 delivered.
