Did we get any further clarification on this? Seems like the M2 is BS and the M2C is AS:

Seems like most mods (even pretty tame ones) push you into BSP/ASP, which feels like a pretty big leap (not about to buy slicks...). Might as well just run STO and be competitive in BS/AS when doing BMW club events ¯\_(ツ)_/¯
