    Do not be fooled by the 4WD and PSM.

    Dear all,
    I own a carrera 4 cab, fantastic car.
    Unfortunately, I had a pretty bad crash a few days ago due to aquaplanning. Which brings me to my point, do not thing that a carrera 4 or turbo is made to drive under the rain, it is made to have more grip in corners and under wet conditions accelerate earlier, but a patch of water will always bring you back to reality especially if you hit at 150 km/h which is not that fast, in fact, it is due to the extreme width of the tyres. So once again, be careful afetr a big storm, is has cost me a lot, but actually, we were fine, the car absorbed the shock extremely well.
    Thank you.
    Oh and RC, I swa the double pipes at Zuffenheusen during a factiry visit and YES, they are very ugly.

    Re: Do not be fooled by the 4WD and PSM.

    Sorry to hear that. Yes, you're right. The PSM/4WD on the C4/C4S and 996 Turbo is mainly for allowing a better cornering control and help to be faster. It is actually also a safety cushion but only to a certain level. When you're too fast, you're too fast, 4WD/PSM can trick physics but only to a certain extent. When its over, its over. I'm sorry you had to learn it the hard way. The "funny" part is: most accidents happening in a 996/Turbo seem to be accidents at high speed on wet pavement. I know several people who had almost the same accident story: wet, Autobahn, around 180-220 kph speed. Nobody got really hurt (despite their pride I guess ) but I don't wish anyone to be in a similar situation. The 911 still loves to shake it's butt, nothing new about it.

    Re: Do not be fooled by the 4WD and PSM.

    Hi RC.

    So these were oversteer crashes with PSM on?

    I have noticed the same thing in the Turbo. Once the Pirellis are about 1/3rd worn, the handling changes dramatically in the wet. The fronts stay attached to the road but the rears easily come unstuck. Quite scary.

    And PSM can only work if the tyres are in contact with the road.

    Which Tyres?

    Hi fixed wing and all,
    This statement about Pirellis worries me.
    My tyres are Pirellis, I know they are supposed to be more sporty than the polyvalent Michelin.
    But I didn't know about the reliability once they are 2/3 used, because guess what, I had 17000 km with one whole day of track which probably corresponds to 2/3 down.
    Should I go for Michelin for a more polyvalent use or Contisportcontact2?
    Thanks.

    Re: Which Tyres?

    My 996 has 17000 km on the clock.
    It is a carrera 4.
    Since it behaves like a RWD, are my rear much more used than my front ones?
    My rear weels are about 2/3 down apparently.
    Should I change the four tyres or just the rear ones and keep the front ones a little longer.
    How do the front ones get worn compared to the rear ones? thanks,
    F.

    Re: Which Tyres?

    The rear ones usually get worn much faster.
    Tread difference between front and rear tires shouldn't exceed around 30%. Sometimes it might be necessary to exchange all four tires.
    I'd stick with the Pirelli.
