Here's my thread around weight reduction and corner weights.
https://f87.bimmerpost.com/forums/sh....php?t=1819724
I don't plan to go as extreme as M2guru here, and am focusing on the "bolt on/bolt off" large weight reduction rocks with the M2. I am at 3370lbs with a full tank of gas and an empty car. Below is my list of mods so far and weight change estimates. The only other thing I'd like to do is an M Performance hood that I am hoping will be good for somewhere between 30 and 35 lbs reduction. And, at some point I'll get a carpet made for the rear seat base and remove that for a net decrease of around 10 more. And on track days, I usually run 513Ms which are around 12lbs lighter than the 437Ms.
