Do you have all season, winter or ultra high performance summer tires? I have the 19" rims with the summer tires so it takes more effort to smoke them as the grip like no one's business. I prefer that so I an have great launches at the stop light with no wheel spin, loads of grip instead of looking like a complete jackass smoking the tires with lots of noise and being slower as a result. I have a RWD car, might be harder to do with x-drive as far as smoking the tires.

With DSC off [hold traction button 10 secs] you can bounce off the limiter [won't up shift] / smoke tires all day long.

What I did was keep it in comfort and turn off DSC (hold traction control button for a few seconds) and then I had my left foot on the brake all the way and then I put my right foot on the gas pedal and revved it up high and then I would take my foot off the brake slowly

This has worked in every automatic I've owned (minus my old 4x4 chevy Silverado lol)

think thats called 'power-braking'.

I always recommend putting it in neutral and then redlining it and then put it Drive with DSC off,etc. That'll do a burnout. (once).

(that process is called neutral slamming). And don't do it if you like your car.

Different roads and weather conditions can affect the launch control but the fact remains you will likely have less wheel spin than without launch control.

If you're talking about the F8x's launch control system, it is a very simple (dumb) launch control system.
It does not learn anything (unlike say the GTR's).
It's essentially there to provide a way of dropping the clutch from a set RPM.

On the F3x the manual does indeed say that "Launch Control adjusts to the surrounding conditions, e.g., wet pavement, when used again." although I do not know the extent to which it does.

It may just be a matter of seeing wheel spin initially and lowering the launch speed after that.

Real question?

In terms of drag racing 'Mercan cars, Auto 2 speed powerglide. Only 1 shift point going down the track. A lot of Super class cars will shift to high gear around the 60' mark then do a brute hp pull in high gear all the way down the track. Those things smoke like crazy.

So many old men on here mad someone wants to have fun. Don't forget to take your centrum silver before bed.

OP, Sports +/DSC off and brake stand. Post vids.

Take this from a 52 year OLD man with a 340i Msport AT, YES you can smoke the rear tires.

Hold down the DSC button until traction and stability controls are completely off.
Press and hold brake pedal with left foot.
Put trans in gear, preferably manual mode, 1st gear.
While holding brake pedal with left foot, press the accel pedal with your other foot, your right foot, that would be your other left.

You will feel the engine RPM rise, and a bit over 2K RPM you will feel the trans lock and the car will feel like it wants to move as the rear end starts to squat down a bit.
Keep your foot on the brake, more pressure on the accel pedal, try around 3000RPM, and then release the brake pedal and keep the accel pedal mashed down.
You'll do a hard smoky launch. If you want harder launch and/or smokier tires, then try a higher RPM before releasing the brake.

Now, if you want to do an old-school style burnout, where you're not really accelerating forward very much but the rear tires are spinning and smoking, that's a bit different.
BMW's, and most cars in general, do not have a "line lock", where you can apply full brake force to the front wheel's brakes, so that you can hold the car stationary while the rear tires can freely light up and burn baby burn.
In cars with no line-lock you have to modulate the brake pedal such that the engine power overcomes a light brake pressure at the rear wheels, while there is also enough brake pressure on the front wheels to keep the car from launching fast and hard forward. The car will still move forward because full brake force can not be applied to the front wheels without affecting the rear.
That takes a bit of practice to get a good balance.


You should really only do this on a safe surface and area, like an empty parking lot, or long driveway where you don't merge into traffic.
That's my "old man" coming out.
But trust me, experience and time creates wisdom, which is something that the young do not have a lot of...yet.
You have to have enough self discipline so that you can have the experience and the time to attain that wisdom that you can then give to the youngsters who will surely come after you.

Just to make sure, you do know that doing big smoky burn-outs WILL create great wear on your tires, right?
And, there is also the potential to ruin a tire even though there is still a lot of tread, because you can "shift" a belt or create internal damage in the tire.
This can also create a tire/wheel balance issue where you may need to have a tire or two re-balanced.
I'm not saying those things will happen, but they can happen because they have happened.

And, realize that when doing the "light brake burn out" you are also adding wear to the rear brakes and they will generate a lot of heat.
This happens because there is still brake fluid pressure to the rear pads to the rotors, and the engine power can overcome that light pressure to start the wheels spinning, and as the wheels spin fast there will be a lot of heat generated by the continuous contact for the brake pads to the rotors.
After big smokey burn out using that technique it's a good idea to drive around slowly with no to little brake pressure to let the pads and rotor cool, and to avoid letting the hot pads rest on a single spot on the very hot rotors.

I think the Mustang has a burnout mode that engages only the front brakes. Also, 50's are the new 30's, case in point Dr. Dre is now in his 50's, Emimem is in his mid-to-late 40's as is Snoop, just for perspective. I myself am 41 but feel like I'm younger. . 50 Cent and Pharrell Williams are around my age. Chuck D and Flavor Flav, 50's. Sorry I'm only referencing rappers as it's my genre of music.

LOL! Yes, I know who all those "older" guys are.

Yes, the Mustang comes with a "line lock".
Of course it is a Pony car that's a fan favorite for drag racers, and the line lock is something cool to give the fans of those cars, the American RWDs with big V8 engines doing smokey burnouts.

I test drove a V8 GT and the 4cyl turbo Mustang.
The turbo Mustang is actually quite nice. In daily driving style and even getting on it once in a while it's very satisfying.
I was much more surprised and impressed at what the 4cyl turbo Mustang could do in comparison to the big V8 GT, as I was expecting more from the V8. But, that was not current and more powerful GT.
I'll have to test drive one of those too.

[omgthedonny]

Lol wow didn’t read comments till today, I was asking just to heat up the tires at track night and doing 1/4 mile runs, not for showing off lol

Typically you see the RWD cars do this to get more traction, I used to have a 300zx twin turbo and that helped a lot before launching on 1/4 runs

Sorry I won’t have any videos doing burn outs lol just going to track night

[BEAR-AvHistory]

Doesn't take much to heat the tires. My 555R 315X35 drag radials heat/clean with a short dry burnout by avoiding the bleach box. Not much for smokey burnouts. But then I am old fart to a 500+HP 2250LB car so being old what do I know.



BTW if the tires are not slipping at launch why do you need a burnout?

[StockLOL]

For you F30 guys who have done burn outs in your cars do both tires spin if you’re going straight? I know we have open diffs unlike the F80’s but in the video posted it looked like both tires spun even sliding to side! Maybe once I’d like to leave two black strips of rubber,if it’s only one tire then I’ll pass.

[insanecoder]

More fun doing donuts

[BEAR-AvHistory]

DSC off should give you an 11 if you can break the tires loose

[scout92]

for sure
