FWIW the gen1 clubsport was a fairly poor GT4 car especially out of the box. Way down on power and much to heavy to be even vaguely competitive against a 570S or a Ginetta.
Isn't that more a failure of BoP though? The 981 clubsport was still made to carry extra ballast in most cases afaik. The 570 gt4 was also made to carry a good bit over 100kg of ballast (plus had significant power restrictions). I don't believe the gt4 cs would have been any heavier than the Mclaren for example in race spec.

One has to note, as far as technical improvements are concerned, the main weakness of the gen 1 car (rear suspension strut design) still remains in this car. Perhaps Porsche simply mean to up their effort in BoP lobbying this time round by supplying a greater number of entries to get a more favourable adjustment.

Poo?
My thoughts exactly. I suppose there are lots of different things in poo, which would make it a 'composite. laugh

Porsche motorsport - now champions at polishing turds. To good effect, I might add.

The new car will be faster than $h!t off a shovel.

Also shows people will buy any $h!t with a Porsche badge.


I'm here all week folks. laugh

Much better to ballast up a lighter car and tweek the power output down of a high output motor than to run flat against the limit out of the box. Ballast goes low down centrally placed rather than randomly scattered around an overweight bus. WTF is that massively heavy PDK box doing hanging out the back? Polar moment of inertia and all that. Fair point about the Cayman rear suspension design, further compromised by the ride height requirements of BOP. Not sure that BOP was/is that unfavorable to the Cayman, it's the easiest excuse in the book. For a competitive GT4 car it is overweight and/or underpowered. A Cayman with the 4.0L GT3 motor would be far more on the money for GT4 racing.

It's also worth mentioning that it's torque that does the work in acceleration ...

A more powerful engine with the top-end restricted will be much more useful in the mid-range than a maxed-out engine with the same max power at the top ... and therefore much less power in the mid-range.

Question: It's an inexpensive process to fit Manthey suspension arms and KW 3 way Clubsport dampers to Manthey spec ... the equivalent of 3.8 X51 performance is already available off the shelf ... and the earlier GT4 gearboxes have proven to be completely resistant to the failures that have affected some later gearboxes (which might therefore limit the desire to make power upgrades to these later cars) ...... I wonder why that change was made to the gearbox ??

Were I to upgrade the engine of my GT4 (an early one as it happens) ... my only real concern would be trackdays noise ... I would want a quiet exhaust !!

P.S. And I won't have to plead with my dealer for an allocation ... how nice.

If the 981 clubsport was already overweight and/or underpowered why were they still being given even more weight as ballast? The whole point of BoP in each class is to allow very different cars to compete on a relatively even basis at a certain price point after all - the big variables are supposed to be fuel/tyre wear/drivability rather than absolute pace. turning up with a lighter/more powerful/more expensively developed car would defeat the entire purpose of gt4 racing.

18" wheels look cool & way nicer that the 20" !!!

IMHO of course .... just nice to see a modern car with some rubber in the profile :-)

And already the BOP engine map was capping power well below 380 so anything more powerful in the old car would be even more useless.

Optimum spec for a GT4 car is around 420-450bhp and 1350-1400kg. More power than that and you’ll get spannerer by more ballast (a la 570S) and any less weight and you’ll get spannerer by power caps (a la KTM X-Bow).

There’s a very good reason things like the M4 and Merc GT GT4 have been competitive straight out the box....

There really should be a sticky on this forum to explain that this statement is incorrect. It is spouted endlessly despite it being absolutely incorrect.

Anyone know if the new GT4 will be available with PDK?
I hope not. If you want a PDK Porsche GT car just get the 991 GT3 or RS.
Don't see what all the fuss is about manual gearboxes. PDK/E-GEAR/F1/DSG whatever is way faster, easier to live with in traffic and does the blips on downshift for you. And anyway, I don't want a GT3/RS I want a PDK GT4 to use as a daily or share with the Mrs (she can't drive manuals). So will it be offered with a choice of gearboxes?
