If not , then you are driving "wrong car"... 640 is a great and suit car for you
No offense but if I'm not mistaken, long time ago you were complaining about squealing noise of your M6 right? I mentioned at that time this noise is normal for high performance cars including Ferrari, Lamborghini and even MB AMG (I posted some forum regardless of your SL AMG with no squealing noise)... The point is : IMHO, M cars are designed to be driven hard and to be pushed to their limits... 100% agree with you about driving hard on public roads or streets is highly prohibited, but there is a major difference between track and street. M6 is not a track oriented car (like 911 or GTR) and no one claimed she is, but it's a high performance car and hard acceleration or pushing the car to the limit must not be an issue at all... and again this hard acceleration is different from track stuff...

Come on now. The fact that you can find hundreds of posts on here (meaning M5/M6 board) about a service bulletin and fix for the brake squeal tells you that it's not normal. It's not even an argument so let's just put that to rest.

I'm just telling you that whether a car is on a street or track makes no difference when it comes to stuff like this. Abusive driving is abusive driving to BMW. I'm using the OP's words....not "I accelerated hard" but rather "I accelerated using the full power output of the car" AKA "I floored the f*ck out of it".
