in winter just dangerous.
What is the minimum temperature to drive safely on cups?
it's very tough as they drop of at 6oc a lot but they are pretty good in the wet now on N2's just not cold and wet.

I came back from Spa was stuck at 55mph on the M1 inside lane in the rain, that was def the max speed I could do and that's not nice in the rain with lorries coming past you at 60 !! that's was circa 15 oc so not even cold.

in winter if a car stops you won't, so you crash it's that simple, you cannot drive to the conditions as people say if there is an issue in front, you would not leave a big enough gap.

There will get load of people say "drive to the conditions" but my view is they are bloody dangerous once cold and then if it rains on top you are just risking life.

Speed bumps are a minor issue, a bigger issue are slopes e.g. driveways, petrol station approaches, multi storey car park ramps etc. The GT4 is low, with a long nose. Scrapes are inevitable on the underside of the nose and on the brake ducts, they're going to happen, but you run the risk of getting stuck if the slopes are steep. No such issues with a GTS.

Cup2s are not all-round tyres, they're sunny days and light rain tyres. My car is weekend use/fun only and rarely goes out between late Nov and early Feb as the temperatures are too low. I would not recommend using Cup2s in winter or when there's a lot of standing water.

You can swap them for PS4Ss which will be much better of course, but that's £1000 on tyres for a brand new car.
And guess what I have a steep downward and slope to get to my home...

No hard and fast rule, but not when it's not warm-ish and dry-ish. Single figure degrees should be treated cautiously.
I suppose the best approach would be to have another set of rims for the winter, but that would be some serious outlay..

This is sounding more and more tricky...maybe GTS was the right decision all along.

Wow, thanks for the warning. Seems that I may need a winter set of rims then.

55mph in the slow lane you are blind for 3 seconds every time a lorry passes you, it's quite scary !! the water covers the whole car...

in the ice cold they understeer like a pig, ie you think, here is a nice round about" and then go straight on for a few yards after turning the wheel with a missed heat beat !!

It's all doable if you don't come across another road issue, you can drive to the conditions if you are the only car on the road.
And you may well make it though winter if you don't come across an accident where you need to stop !

BUT if you need to stop in the cold and wet even with the 4 second rule you will still hit the car in front.

The GT4 is compromised as an everyday car, the GTS is the all-rounder. Porsche are very good at making a range of cars that suit different needs.

Your story reminds of the days I worked in tech support, 24 hrs on call. I used to get paged out at 1am by Japan or Hong Kong, jump into the shower then drive on the m25 in the rain with lorry’s passing me and it was truly scary.

Not sure you can if you want to stay N rated? I’ve been searching but can’t find the rears (295/30) anywhere - not sure they make them? If anyone can point me to them then I would be eternally grateful as I really don’t like the Cup2’s. Had a few brown trouser moments in my GT3 with them and was disappointed that after AP labelled the Spyder a ‘road car’ they still delivered them on Cup2’s. The only N rated options I can currently find in the size are SportMaxx, Cup2 and P Zero, a pretty dire selection unfortunately. May have to end up on P Zeros to use in winter conditions, but I’d much rather the PS4S.

Going to treat the front diffuser and brake ducts as consumables anyway...
These are generally fine if you take them slowly one wheel on one wheel off - middling them is a lot more likely to scrape.

Good point about N rated, I forgot about that. Dunlops will be the same as the Cup2s I reckon, so that leaves Pirellis. No choice really - live with Cup2s!

The GT4 my OPC has for sale has Dunlops on it.

Maybe not all the cars are delivered with Cup tyres?

Yes I will probably have to but it’s a real shame as I like to use my cars in all weather. I have had a very similar experience to 911R in my GT3, caught in a deluge and nursing it home in the inside lane was a thoroughly unenjoyable experience!

I note that you can specify summer tyres now on the Spyder - which I will if they ever launch the bloody PDK !! Strange that this is not an option on GT 4

No, they get Cup2 or Sportmaxx but both are semi-slick summer tyres.

I agree with this as it happened to me in my RS WP..Last February driving on a very busy M4 in torrential rain and we hit a sudden blanket of thick compacted slushy snow..I was only doing 50 MPH thank god due the rain however all cars in front of me slammed their brakes on when we hit the snow..I had to brake to avoid a rear end collision and the RS's Cups acted like ice pucks with zero braking and steering..Luckily in the heat of the moment when i realised a collision was unavoidable i decided to use the central reservation's kerb to stop the car..It worked a treat however by sustaining some cosmetic front driver's side damage..
Cups are fine when its either dry and cold, or wet and warm, but the combination of very wet and very cold is simply inviting the grim reaper to come to get you.!

Yes definitely compared to the Cups, but they’re not a patch on the PS4S overall.

Has anyone driven both the GTS 4.0 and GT4 and how do they compare?

What are the expected residuals after 3 years?

Which GTS chassis? -10mm or -20mm?

I've not driven the GTS but I will guess based on individual reviews and specs:

  • they're pretty similar in engine performance with the GTS having a 200rpm lower redine
  • the -20mm chassis feels a bit softer and more comfortable than the GT4 and much less likely to scrape, the -10mm even more so
  • GT4 residuals will be quoted as a bit more than the GTS due to the higher initial price
