Honestly don’t know.
My statement is based on 20 years of analyzing post-test bearings and analyzing failed bearings. Your disagreement is based on what? What was this wear?... electrical erosion, abrasive damage, asperity wear, spalling?
Is a flying start harder for the diff and even transmission compared to a rolling start? When i got a tuning on my previous car, a Bmw E39 530Dat with a GM 5L40E transmission the torque was higher than the transmission was rated for, i remember the tuner said: "no problem, just avoid flying starts" let the car roll before you floor it. I always did and still do with my current car. I never floor it when standing still, get the 2 tons rolling first I know there is alot of electronics today controlling torque in some gears and there is antispin and stuff so is there anything in this theory?
