Aftermarket turbo tunes = the same reliability and safety as stock on track? not in my experience, not on any platform I've seen. If there really is no difference in components btwn C and CS, and the factory CS software becomes known/available, then sure.

I do think that the reliable 39 bhp boost in combination with (presumably) extra cooling capability and improved engine management is one of the advantages being overlooked here. If the CS cools 1/2 as good as the GTS, then you won't have to give a 2nd thought to engine temps. The same cannot be said for most aftermarket tuned turbo cars on track.

On a general note: I cannot say that I am totally unfamiliar with what the M2 CS is about. I know a couple of things about that car. And though I've never driven it, I genuinely trust that it will be a fine piece of automotive machinery. Anyways, if you'd ever read some of my M2 CS posts, you'd know that I ain't "looking to dismiss, or pick holes". I respect BMW, but am not affiliated to them, which gives me a bit more freedom to express what I like and dislike. Feel free to disagree.
