Yes you can do the 18x9.0" ET31 squared setup on your LCI e92 M-sport. On the front of your e92, for the 18x9" ET31 we recommend a 245/40/18 street for it to fit without issues, since a 255/35/18 would require about negative 2 degrees of camber to clear.
The rears may need a light fender roll for the 255/35/18 street tire to not rub on the rears. The 245/35/18 street tire should clear the rears without any issues, as long as it's not an extreme performance tire such as the Hankook RS3 or Dunlop Star Specs.
