It’ll be the low temperature.

MPS4S are way better than Pzero as said above

Think most of the answers are already said & done,
I had a mate who stuffed his new c2 into the Armco on a straight wet road giving it a blip, they are a pendulum when they let loose.

My guess is heavy right foot & cold temperature's, I must admit I was pretty crap at saving them at Silverstone's Porsche facility in the wet.

Modern sporting cars like the Porsche have amazing suspension and levels of grip and we get used to it.

However, in the wet as others have said, aquaplaning can dramatically reduce levels of grip. The grip in these conditions (and even worse on ice) is really determined by the tyres and pretty independent of the car itself - you may be no better than any other car. Of course, this is a much larger difference between wet and dry than you might get from a basic hatchback.

Those of us who in their youth and beyond pushed our luck out there on two wheels ... and survived.... Learned faaaast to READ the road surface and how it changed from yard to yard, mile to mile, day to day, season to season, and part of that learning process may have involved gravel rash, which was a real pain when picking those little stones out from under the skin on one`s knees... Not something quickly forgotten..?

Road repairs I think known as overbanding, generally provide far less grip that the surrounding road surface best not to accelerate or brake on any of that..?

In Autmn the leaves can cause real issues even when the sun is shining as they can shelter the frost below which has already melted on the rest of the bare Tarmac

The same leaves once crushed to pulp by traffic do not provide a surface with much in the way of grip and less so when applying power out of the apex...

Bus routes in cities and perhaps more so bus stops can be diesel infected, tight corners likewise caused by diesel spills from over filled tanks, not much grip on diesel.... ouch!

The first rain shower after a long hot spell should be treated as if the road was covered in frost...especially on those bus or HGV routes and inner lanes of roads..

Sure some tyres are better than others, just as some drivers have a bit more understanding of the road surface than others.

Perhaps best to remember it is still possible for a great driver to spin the best handling car in the world on the very best tyres for the prevailing conditions... F1 drivers do it in the wet and the dry just about every weekend in the Summer.. Question

Michelins are simply the best all round...very good in the damp and wet.

As people have said obviously verify correct tyre pressures.

At a minimum I would get a local Geometry done.

At best ( a long way, I know) but the boys at Centre Gravity will transform your car to the way it should be and better!! Thumb

Ive done colossal speeds in the wet on my many trips to and from Germany on the autobahns (in my 993) over the years...
-Worn Pirellis=Lethal!
-Poor Geometery= Lethal!
-Properly set up=Fine!
-Centre Gravity set up= Fantastic!

Your GTS should be a lot better than a 993!

Coming form a 997 C4S, to the 430 BHP 991 engine, I’d say there’s absolutely nowt wrong, other than the summer tyres, and the brand!

Mine is exactly the same in the wet and cold, the back end is all over the place with the right foot down. I’d only worry if it’s like that in the dry with decent tyres or with winters fitted at this time of year.

The worse brand of tyre for winter, cold temps, wet roads and 2 wheel drive do not mix at all. And yes I’m also on Pirelli’s which is also a big part of your problem.

get winter tyres!! I have them on mine and my 997 feels epic on them.

especially for the coming months. well worth doing and being in control rather than having a big one that could be a lot more expensive than a set of winters!

massive wide summer tyres are utter shite in this weather,

Mine lit up its rears as it went into 3rd gear coming off a slip road on the A3 tonight. Crossing the white lines was the main cause of it (and driving like a numpty). Traction control and a lift off brought everything back into line. I’ve got 4mm on my rear Pirelli’s left. They are truly 💩 in the cold and wet.
Michelin’s everyday when possible.

I’m actually really pleased to read this thread. I thought I was the only one. 2s here, on p Zerros, and the slightest bit of wet and the back end is out when it really shouldn’t be! Yes I’ve had the geo checked.
Annoyingly I need New pair of rears but the fronts are good, so I’ve gotta get a pair of pzeros again as I don’t feel it’s good to mix brands front and rear.
