Our new T56 6-speed H-pattern 6-speed swap kit for the BMW S58 engine is in place and installed in my G80 M3.
See the kit --> G80 M3 T56 Kit
This is a factory manual car so the swap was pretty straightforward, but you can do an auto-to-manual swap on your automatic M3 (non x-drive, rear wheel drive only) by utilizing a few OEM parts like clutch clutch pedal, clutch master cylinder, and interior panel.
