As far as BMW is concerned, I believe that BMW will not warrant parts failure due to excessive use of launch control. For example my understanding is that on 'M' series cars, they can only do 5? launch controls before the car is considered out of warranty, particularly the clutch.......There is no doubt that to my mind the stresses placed on components is very high and bear in mind that when they read the Key/ECU they know what you have been upto!!!!
