That’s good to hear the stock cooling system can handle the extra grip! I think the extra grip is going to work the cooling system more because you can stay on the power longer (brake later) and get on the power earlier (corner exit). Small changes on a single corner, but in a 20 minute session it can add up. On the M2 at least, it is not a meaningful amount of thermal load increase. Likely because the M3/4 cooling system is carried over from a higher powered and slightly heavier vehicle. And certainly work the diff more
I’d be interest to see some temperature differences between street tires and take offs.
