i just read on pistonheads that it might be possible to disengage the 4WD on a C4S by clicking the handbrake on one notch:

I ended up driving the C4S with the handbrake on one click (which disengages the 4WD)

can anyone confirm this or is it wishful thinking? if it isn't, i'd be tempted to try it the next time i'm on a track to see compare and contrast the difference between 2WD and 4WD....
 
Sounds as if you could do some damage to the handbrake.

I wouldn't do this if I were you.

As for the effect on any warranty or your insurance if you have an accident ... does not bear thinking about.

Absolute tosh, I'm afraid.

as i suspected tbh!

i wonder if it would be possible for porsche to put a feature in on their 4WD 911s whereby you could 'disable' the 4WD with a button push depending on what kind of handling you felt like that day....

well, i was thinking that the first click on the hand brake of every other car i've owned does nothing apart from make a light on the dash switch on :p anyway, it's apparently pointless so no need to even risk it :)
 
I believe that works on Haldex cars...the Audi S3s and R32 Golfs etc with the Hladex controlled centre clutch definately do something when the handbrake is activated - can't remember if it's a complete disconnection of torque to the rear, or just a fixed split...I think it stops rear drive completely.

 
There's an explanation <HERE>

Play the video - it's quite nice.

Trouble is, I'm wishing my life away waiting for them to reach my price bracket. I had my mind set on a 997T Tip as my next car (some while yet), but now it looks like I might have to wait even longer for a Gen 2 PDK. [:mad:]
