"General Use of Launch Control causes premature component wear, as the function subjects the vehicle to very high stresses and loads. Do not use Launch Control when running in. When starting with Launch Control, do not turn the steering wheel."
Then why didn't you say that instead of a condescending reference to plenty of books to browse?

My owner's manual is in the glovebox, in the car, in Germany.

The question I posed was truly inquisitive, and your comment piqued my interest enough that I did some research and found the thread that I reference. There was dispute in that thread and the issue was left unresolved. Hence my question.

It doesn't take a rocket scientist to figure out that driving a car hard causes more wear than normal driving. We are all trying to figure out where the line is between having fun with the car and breaking it.

I will use this as a point of reference, and continue to research the issue, but am not convinced that BMW thought the car was strong enough to include a launch control but that occasional use will cause damage. I.e., the warning is likely just from the legal department.

I just don't get the "I got a secret" mentality.

My 992 C2S is a few dollars cheaper to insure despite being twice as expensive as my prior M4.

The number is actually 100 and then yes the gear shifts are slower.

Looks like they finally tested the AWD version.

2.8s to 60 and 11.0s 1/4 mile @125mph. Insane supercar-like figures.

Sometimes I think about what I'm giving up by going with the non comp 6MT RWD. But at the end of the day it's all about having fun over spreadsheet numbers.

Why it's a fact that 100 is the limit (not 50) and then the transmission shifts slower.

And if it's just speculation, that's cool. But completely worthless.
I speculate that it sounds like you don't know what you're talking about. So provide some evidence of your claim, or my speculation will turn to certainty.

Why are you stalking me?
For what it's worth, to you both, have a chat to your service manager and ask why does BMW occasionally void the car warranty of a car where launch control has been used too often.

It's a revelation no one should miss out on

They do factor in the stress and limit LC to 100 times before the transmission slows down the shifts when in use.

The clock doesn't start on acceleration runs right when the vehicles start rolling. This practice, which is commonly called rollout, comes from the drag strip, where it's possible for a car to travel a foot or more before it trips the timing light that actually starts the clock.

The industry standard calls for a one-foot rollout before a timed run begins. Our old test equipment couldn't measure that precisely, so we approximated a foot by beginning our runs at 3 mph. That was a fair estimate when cars didn't launch as hard as they do today, but gains in traction, launch control, and horsepower have rendered our 3-mph approximation increasingly obsolete. Our GPS-based Racelogic VBox test equipment is accurate enough to measure the first foot of rollout, so starting with the December 2019 issue, we're changing our acceleration reporting.

Lining up a vehicle at a drag strip requires careful placement of the front tires relative to two beams of light. When a car's front tire crosses the first one, a "prestage" warning is lit. When the tire interrupts the second beam—the "stage beam," which is seven inches ahead—the car is staged and ready for a run. The clock starts when the car's tire moves enough to uncover the second light beam. The distance the car travels before the stage beam is uncovered (and therefore the timing begins) is what's known as rollout, and it can vary from nothing to more than a foot. Obviously, this affects the elapsed time, sometimes by as much as 0.3 second. Our testing now adopts the industry-standard one-foot rollout.
Very interesting, thanks for posting that!

So Dragy times would not have this "roll-out" factored in?

And is your belief that the C&D time is a "roll-out" drag strip time?
Yes C&D times always have their adjusted number and they typically tell you as much in each post. However, they go a bit more into the weeds here;

https://www.caranddriver.com/feature...-we-test-cars/

"All of our standing-start acceleration times also include rollout, a short period of time (typically about 0.3 second) that we subtract from the acceleration figures. It's a phenomenon that stems from the physics of the timing lights at a drag strip, where a car can be rolling for 12 inches or more before the clock starts."

If their best run had a Dragy video to accompany — you'd likely see a .3 second slower time on it than what ends up in the magazine.

12.4 @ 116 versus 125 in the 1/4. Or even 122. 6-9mph in the 1/4 isn't even a contest. 12.4 to an 10.8 or even an 11.2, isn't even a contest.

No, it's like taste testing 3 different types of oranges. They're the 3 main M cars and I think it would be a neat race. The Porsche 911 is a RADICALLY different car compared to an M3/4, but people compare them all of the time.
