Snetterton is not one of my strongest track in nailing a complete lap.

All purple sectors combined should get me a 45.3 so there is a lot of time in this setup/car.

You do not want to overdrive the car on this track, just keep it clean, make sure you open the steering wheel

when going on the throttle in corners like Hamilton and Williams. 

You can always run brake bias at 55%, that can help in a corner like Brundle to Nelson.

For questions only about the setup you can DM me, you can find me at Nils Naujoks his discord in the BMW M2/M4/M6 section:
