Prospective 981 GT4 Owners Discussion Forum.

To those who have a car what is the buffeting like with the windows down? In my 991S I could barely go above 40mph with the windows down without the buffeting driving me mad. For the GT4 though, sounds like the windows have to be down for the exhaust to be properly appreciated.

As long as both windows are down there's no buffeting. At 100 km/h with one window down it's unbearable so make sure your passenger likes fresh air.

I can think of a few cars which might be better at 1/2 the price :-). But it's great we are seeing some exciting reviews.

Maybe if you're a pro and also willing to sacrifice some crash protection but I can't think of anything else that would give a mere enthusiast such as myself the confidence to go that hard.

Someone asked recently how you adjust the rear wing. The manual just has a small ambiguous diagram but I'm guessing that the horizontal screws at the top of the brackets have a cam effect and that you turn the heads on one side of the bracket one way and the heads on the other side the opposite way.

UNDERSTEER! Exactly what I experienced at Silverstone PEC. Still very happy with the last qoute... Spend six months tuning this out to be the happiest six months of your life 😀

3.5 sec to 60 with "normal" gearing...

[PorscheGT4]

so backs up my PEC review :-)

understeers and long gearing.

Was still quicker than R8v10 and 458 though!

CUP 2 are mighty tyres for lap times, the Audi would have been on Bridgestone road tyres, and the 458 Standard Pirelli P zero ?

Must say, great vlog to watch, Tim is one very lucky boy!

I don't disagree with you there, I have no idea of Shmee's history, but I'm certainly not a fan of all these 'rich kids' pretending to have jobs and driving around in borrowed supercars all day every day; but I liked this particular vlog because of the cars involved; oh to have been in that courtyard area (I'm a sucker for modern cars, not so much the classics).

That's was me, thanks for the information

I would assume they(tyres)have a big impact but even so these are cars with just a touch under 600bhp ,and they are not slouches around the bend so its still mighty impressive,if irrelevant for the vast majority of us.

I agree with cmoose: I can't see understeer being an issue in the slightest. For the blokes in the video to have complained about it so much and still not been entirely satisfied after Porsche adjusted it I reckon:
a) They must have started with the rear ARB soft like PorscheGT4 was unlucky enough to cop on his PEC car;
b) When they complained, Porsche must have just changed back to the standard setup (medium front and rear); and
c) With the standard setup - Walter Röhrl's favourite - they didn't drive like Walter, who probably backs it in to corners (and in the GT4 matched his 'Ring time in the 997.2 GT3, which has 50hp more).
As I posted previously, in road driving (not backing it in) I experienced slight understeer with the standard setup (but still way more front end grip than in anything else I've driven), but after setting the rear ARB to stiff found the handling to be superbly neutral and throttle adjustable. The difference was very noticeable so I'm sure that continuing on to set the front to soft would make it very oversteery. And that's without adjusting camber or anything else.

Hi all

I really need to stop reading this forum!!

So I've diddly squat chance of getting a GT4, I have just sold my 993 and looking for something else, I am thinking at mo about a Cayman GTS or and I know this is not really the right page for this marque but would appreciate any thoughts, the new Elise 220 cup.

I have never driven an Elise, or any Lotus for that matter so I am going to JCTs in Leeds this week for a test drive, now I know the Elise is going to be raw, no frills, noisy and impractical but as it will be a second car I thought would obviously tick the odd track day and road trip box.

Hope you don't mind me butting in on the thread, i just thought some of you guys would of had an Elise/ Cayman at some point, any thoughts/ comments would be appreciated, I never used the 993 so basically looking for something to have some fun in
Cheers Lee
