I haven’t upgraded to a M2C (yet) but I’m in the same boat as you. The decision to upgrade depends on the ultimate goal in mind. Upgrading cooling only takes you so far as documented by ZM2 but arguably it’s pretty damn far.
While there isn’t limitless headroom to be found with cooling upgrades, there are things you can do so the question is simply do your goals fit within what’s possible with upgrades.
If your goals for the car take you beyond what can be supported, then it’s worth making the switch.
In your region, that may only be ~415whp but a properly setup M2 with that power is a plenty quick track tool. It won’t be the 6-700whp monster you see at Super Lap Battle but it will be plenty potent.
TLDR
If you want to track more than say 450whp in real high temps then an S55 F87 is the move. If 400-450whp is enough, the OG will serve you well if you throw the full list of cooling upgrades at it.
Personally, I don’t need more cooling right now, I need more coaching and more seat time.
