How To Do A Burnout In an Automatic 

Would a Mercedes GLK220 Or 250 work?

yes

Thanks!

Impossible with AWD i guess

There's always Hoonicorn style: use a tow rope or something and tie off from the rear to something that won't move, then apply throttle, preferably on a loose surface.

Every car manufacturer sets their throttle cut sensitivity differently, it all depends on what you are driving. Some vehicles you really can't do anything to prevent throttle cutting without doing some serious computer modifications.

because the car dives onto the front wheels, so they have more grip, think of a motorcycle doing a stoppie (wheelie under braking), do you think with the rear wheel in the air, that using the rear brake would slow you down? no, and a car does the same thing, the rear wheels dont quite leave the ground, but since all the weight is on the front, the front has more grip, so it can brake harder. So they make it so when you press the brakes most of the braking force is sent to the front, normaly about 80/20 split

When you brake, more weight is shifted towards the front of the car meaning the front tires will have more grip than compared to the rear. This means you can apply more braking force to the front tires before they lock up than the rear. Additionally it's more of a safety feature where locking the front tires will cause understeer so you'll collide with an object head on. If the rear tires lock up from braking force, the car will want to oversteer, so a collision would more likely be a side impact (Which is less safe than a frontal collision).

oh yea thats true

Doesn't this fuck your trans up? I was always told it did but idk I never did burnouts only drifts lol.

With 4 wheel drive, you could potentially if you are on a loose surface and your vehicle has enough horsepower, however something would most likely break and damage the vehicle. Rear wheel drive is ideal for doing a burnout.

4 years is old to you? I see my 89 as practically new
