I can quote a well known poster who drifts his M5 f10 in the Middle East regularily.At 75000mi or thereabouts he had his rod bearings replaced as a precaution and surprisingly the old ones were hardly worn in fact they were perfect.He says the secret to S63TT engine longevity is to gradually to warm up the engine then have the fun. When finished a gradual cool down drive to get the temps down before switching off makes a lot of sense to me and I am employing these tactics also as I plan on keeping my '13 for quite a while.
Who knows the engine builders may start complaining
