I know a vehicle is merely a collection of parts working in unison together but one would never be able to properly mimic a CS from Competition base simply because of the carbon fiber roof and Adaptive Suspension being mechanically and cost-prohibited. The end.
Also, some of you guys are true hypocrites; when a 335i/340i owner adds a M4 part or a M235i/M240i adds a M2 piece, he's a poser but yet some of you want to create a makeshift M2 CS.
Stay in your lane, people..
