Ok, so I must admit I was already skeptical about the notion that turning psm off and engaging the e-brake one click would disengage the front wheels. So, I tried it and as far as I can tell, nothing happens. Below is a video I took. It was cold out but you can see the back AND front wheels start to spin as soon as I lift off the brake. The youtube video below is average quality but on the high-def version you can see the front and back spinning. As far as I'm concerned the one-click brake/2wd is false. Too bad, it would have been cool.

 

It's PSM off and two clicks... It works on my 2007 tip

 

Hahaha, no wait, it's 3 clicks and the turbos shut down, 4 clicks and the car goes into valet mode, and 5 clicks to enter a secret launch control mode. Sorry, you guys are riding the goat with this one.

 

I'd never heard about this. How many clicks to get my tip into PDK mode?

 

Maybe you should try this in the grass or snow?

 

More likely for you to find snow - go for it.

 

holy **** i cant believe someone actually did this.
. sport mode on - the car is more rwd bias.
sport mode off- the car distributes more power to the front (via the transparent center diff).

pulling the ebrake does not do anything.
if you want to do awd burnouts, launch the car at and incline, rev to 5500 and drop the clutch, it wouldnt hurt to put 50lbs of air in your tires either. this is how you do a super easy burnout. bald tires, low fuel etc.

this thread has the potential for to become a classic such as these threads from back in the day...

Trust me, one click doesn't do $hit. I've towed a 7000 pound boat home once in my truck not realizing the ebrake was halfway on. One click isn't anything. It's when I tried the 4 clicks to go to valet mode that I realized the car was limited to 20 mph!

 

the only thing that will burn out is the rear brake pads. lol

OP- replace your passenger side brake light.
