That's the first thing I thought too.

But Max rear is For wet track. @ M4 GTS, well the F1 comparsion is not that solid. Due to 99% will only need to drive 2 setting on the GTS, that would be street or track setting. As well Max aero rear For enhanced wet gripp. Or are you saying you could find a better overall setting among the 2500 possible?

My guess is no, we could do fine on most tracks in track setting, and street setting on Nur.

just to add to my homie's VCP and M4_GTS:

Walter Haupt the lead technical engineer...straight told me and another owner who is just a total lurker on this site, his recommendation is to set aero to MAX attack.. yes you give up Vmax but only on the longest of tracks with long straights. and recommends dropping the suspension off the highest setting so the car is lower on the front...so it is almost pitched forward slightly....

which I think most of us have done....however the ring time higher settings.

My best guess would be to make the DCT happy and shift higher then second gear. I put the seat belt on when on the dyno for that reason.

I know For sure a wet setting on fast Nurburgring will slow you down up and down them fast sections.

When Bill Auberlen says "Give me max downforce," you give him max downforce. No questions.

A pretty awesome ride along

Racing harness to tight him to the seat, and stock one to get rid of the stupid seatbelt warning

Otherwise warning gong for the entire session! lol

[Captain Unknown GT4]

Agree, that was also what I told BMW, put it to Max downforce front/rear. Then again I look at rear wing and It was very steep angle. Hence I read cars trackbook. There the answer was-Max rear aero is to get enhanced wet grip.

Sure I agree to much of this. But, and this Is a big But, how on earth will 95% of the GTS owners get the end set up that make them faster? I know we know For a fact not many datalogg before and after test when they are on the average trackay. So in the end the most people will only have a feeling if the car now is faster or slower etc. And that feeling is far from hard datatrace, consistent testning fact.

This car also got mecanical grip, and also provide aero grip on setting nr.2 hence not al driver will need Max aero on a dry track. not them who dont mind a loser rear end, but want Maximum vmax on fast track.

I am not saying I know whats what, all I say try the car in aero 2. Reason is BMW M have extensive testning and nr 3 is For wet track. If It was not, BMW would not print it in book. The book I know many not even have read aparently.

[Haywood]

The car is the real deal. I love that track so much. Driven it a few times. Obviously, never like this!

Damage control? Perhaps the GTS hasn't set the press on fire as expected.

Seatbelt chime?

Really doubt it. On the grand course it is 7 sec faster than the regular M4.

What does a fully stock M4 do on the full course?

Yes - it's a production vehicle.

[Fake News 2017]

Hell, he explained in the video why he was using max downforce wing....

Donney Isley with BMW ran a 2:09.6 with an early production stock M4, so prob more like low 2:00's for the GTS.

He just said its Max downforce, we all know that. The thing is most people dont know that BMW M set Max aero rear For wet track use.

I am just pointing that out, and I am not trying to be bad , just saying.
I know alot of people that dont have a clu about this. Me to initaly, but I learn this when I finaly read m4 Gts track book that come with car.

You still don't have a clue and don't get it. So according to the book, you should only use the 2 settings provided. All the other "clicks" on the suspension adjustment knobs are all useless and just there for no reason.

I think you should just buy a regular M4 and stick with the 3 settings with the adaptive suspension. I am done with trying to explain this to you. It just seems like you are stuck in your little world of "following the book". It's your car, do whatever you want with it.

Correct the safety system does not take kindly to seeing the seatbelt un harnessed. Good call.

That looked fun.

Sure speaks volumes when Bill was unable to talk due to how involved he was

Maybe it's just a language barrier, but it seems like you're way overthinking this. First, very few people are going to participate in timed events with their GTS, so honestly, it really does come down to preference. Also, for the vast majority of drivers, reducing lap times has way more to do with the driver than it does the car setup. If more aero provides more grip, and that gives the driver more confidence, then max aero might deliver faster lap times. You don't need data logging to arrive at that conclusion.

What BMW have printed in the book are guidelines. There is no way they could say that max aero is only for use in the wet. That flies in the face of everything you'll learn about aero setup if you were to go and learn something about how to tune a car for racing. Balancing mechanical grip, aero grip, and vmax benefits is a difficult chore, and it varies from circuit to circuit.

This isn't F1. It's a production car with a great adjustable suspension and aero package that will be driven by owners at HDPE and track day events, many of which prohibit timing altogether.
