I did some searching but couldn't find a concise Z4M weight reduction strategy thread. Seeing that many of you have removed stock components and actually weighed them, would you be willing to post component weights (as accurate as you can get)?

I'll be posting in here as I weigh various components on my end (I have scales and even do my own corner balancing for the ultimate weight comparisons). Here are some components which seem to be common for removal:
