Think Spyder same suspension as GTS so not as stiff as GT4
It probably has more travel available than the GT cars due to higher ride height as well.

Lol you think its acceptable to blow a turret if the car has had a lowered ride height. Most people lowering these cars will be putting springs matched to dampers, i.e a full kit. It shouldn't happen period. Ive lowered loads of cars, road cars, race cars, hit sausage kerbs on track and no issue. This is definitely a weakness.
Well that's slightly overstating things. It is a design issue yes but within PAG's recommended ride height settings I don't think it has by and large been a problem. Just because you could take a car out of spec by lowering it doesn't mean you should necessarily expect to be able to do so for another car imo. That said at minimum Porsche should probably have explicitly stated that the cars should not be lowered on OEM springs more than a certain amount (although I suppose they could point to their recommend ride height range).

Are the dampers ride height adjustable on a GT3?

Yes
Lowering a car that comes with adjustable height dampers shouldn't really be a reason or part of the reason a turret blows, or used an excuse. At the end of the day the turrets are a weak point.

I think it's more about lowering the car more than the standard adjustment on the GT cars that Porsche allows for....

Well it depends. Just because something can be adjusted beyond say point X doesn't mean it should be either and if you're adjusting out of the manufacturer recommended range it's not exactly their fault if something goes wrong. And yes I agree the turrets are a weak point but within the OEM parameters it isn't obviously an issue.

Porsche Motorsport offer Turret supports that are intended to spread excessive load.
My KW 3-way Clubsport dampers seem to absorb kerb shock in a way that disturbs the car far less than the PASM system did ... so I assume they will also be better than stock in terms of prospective Turret damage.
Irrespective, the supports are not expensive to fit so I will do this. Cheap insurance.

Manthey Racing lower all their cars which go though them for mods, GT2, 3 and 4's

I think they just limit damage to surrounding area's , nothing more, but yes maybe worth fitting

I think you are probably right that the evidence where Turrets have failed with the support fitted, is that damage has been more limited.
But it's difficult to argue from this that a car with the support fitted is no less likely to fail than one without it ...
As an aside, for insurance purposes where an incident has arisen, it might be very convenient to argue that it was caused by Turret failure rather than driver error of some sort ....

So who thinks Porsche May have an issue with the new 718 gt4?

Does it feel like this on show testing has gone on far longer than normal?

I think they have a massive issue. The GT3/Speedster engines needed ITBs to pair with the GPF, there's no way the GT4 will have them due to the increased cost.

I wonder what the plan is now...

As mentioned in another thread evidently according to this week's Autocar test of the new Speedster this GT3 engine now sounds crap compared to the 991.2 GT3 unit pre filter.

Hopefully the 718 GT4 may escape this but in all probability it won't.

Just replied on the other thread. Open eye insight from Autocar, how on earth are they going to fix it?

Just put no mufflers?

I’ve just read the article and couldn’t find any reference to it sounding crap..

‘New particulate filters have diluted the manic engine note – bluntly, it’s now a little less ‘motorsport’, if still utterly magnificent...’

I read a Speedster review that was more explanatory regarding the Speedster's noise compared to a GT3..It basically said that the closed part behind the seats with the huge C/F back coupled with the folded top acted in significantly muffling the intake noise from the engine..This makes sense and another point where a top Porsche guy was quoted as saying that the Speedster was made quieter than the RS to suit touring better..

Highly speculative and contrary to known info.

Audi has an NA R8 with the filters and no ITBs and a far higher specific output than the GT4 is likely to have. ITBs not remotely necessary for the kind of output the GT4 will have.

The challenge with the GT3 engine is to maintain that really high specific output. GT4 does not have anything like that problem.

Fair points, filter only it is then.

And to think none of us could imagine that all the conjecture, rumours and false dawns of the 981 GT4 would pale into insignificance when compared with the 718 GT4 arrival...…

Porsche - masters of illusion featuring extensive smoke & mirrors!

McLaren would have launched 86 new models in the same time (LOL) but also failed to win any competitive motorsport or even qualify for their US adventure
