I usually have a trick for off the lights grip. It needs a strong e brake. Push the e brakes as hard as u can load the engine a little so the car sags at the rear then with ur left foot press as hard as u can on the brakes and give it more gaz to say 2200 Rpm. And release all brakes. This puts weight on the rear tires and reduces spin thou I doubt ur w140 can spin due to it's weight. The v8 500 I have on skinny tires and hardly spins.

Any way I learned this trick on manual cars thou there I don't use the foot brake. I just pull the hand brake. Hold revs at what ever rpm I need and have the clutch bite a little just long enough to load the rear tires as the car sags. And then launch the car.
