I've had more than a few M3's, all of them would creep past 210 going uphill. I've got this one mountain that I climb frequently and even in the winter that load puts the needle past 210...no AC either. Once I level out, it's back to just a hair under 210. This was on brand new M3's, all under 7K miles. I wouldn't worry about higher temps under greater loads.
