Allocations, no, but at the end sticker was possible for on the ground non-heritage, non-PTS speedys. 991.2 RS were ADM and then back to sticker and now below.

The same car that has the intakes on the side rear windows?
A system that ended up in the Clubsports to help them make a few more ponies and level the playing field...that to me says test mule for CS upgrades.
But we will see as time is running out for PAG to launch an RS version....

At least on the rear bigger tire and wheel is a no-go......unless they heavily modify the rear suspension and/or body in white which is doubtful.

Agree here, there is no room for a wider wheel in the rear.

Now the front, maybe... The front is a little more tucked in on the GT4 than the rear, so there is room to widen the wheel a little and maybe put a 265 up front, which when calibrated with all the software and maybe some hardware changes to account for the wider front wheel/tire, will give the GT4 RS more front end grip, similar to how the GT3 RS has more front end grip then the standard GT3.

I've got the 718GT4 but if this RS is a manual, I'll be on to it like a Seagull on a chip. Otherwise nahhh.

JAhmed

Yup. This is what I'm told. 01/2021 launch, US deliveries Fall 2021.

I wonder if the end design for the cold air intake in the rear quarter window will end up looking like the one on the GT4CS MR?

I would imagine rain or water Ingress would be an issue?

jmartpr

I gave it almost zero chances that any street car would have a design like that......while this is functional for the engine it will be bad for the little cabin of a Cayman.
I also wonder about sound insulation and suppression when you have a big horn right next to your head....and I don't use my helmet and comm system on the street

CAlexio

I share the same questions... but I remain intrigued at what the vents are on the mule then? Porsche doesn't do fake vents

IMHO the CS design doesn't lend iself to be included in a consumer application; big round tubing in the interior, big NACA inlet, etc.

For a consumer application I can see that louvered approach (DOT regulations have to be met for debris, etc.) feeding a more rectangular duct that feeds those little storage cubbies by those rear windows and from there gets funneled into the ducting already in the car from the side. This might have the side benefit of alleviating water ingress and drainage (since flow is down hill). Depending on interior design there may be a chance for a thin layer of sound insulation that could be incorporated.

CAlexio

That's a good wag.. I also though that the intake tubes would have to be cleaned up for production.

But why is there a regulatory or rain concern for that upper vent when the lower one (by the doors) doesn't have that issue? It's only a few inches higher..

jmartpr

It's more than a few inches.....On the lower one water would have to travel up to the engine intake while on the one on the CS it can flow down into the engine...not good...unless they have some kind of drainage system before the TB.

jmartpr

One thing Porsche could have learned from Singer is how they did a similar system on the DLS model...the naca duct is made from clear plastic.

CAlexio

Exactly to this point, there are many production cars with intakes above the engine... Starting with a countach in the 1970s, to many exotics in production today. So on this point alone, I still don't see the issue.

With the window intake on the MR being so clean and already proven, and with the GT4rs looking more and more like a street registerable version of the GT4rs, my WAG is that aside from the tubing which is going to get very neatlyIntegrated into some hard plastic fully enclosed plumbing, We're going to get a car which is at least on the exterior basically identical except for the roll down windows.

jmartpr

The issue is that all of those cars were designed from zero with that intake in mind......integrating after you have designed a car is not so simple: space, water drainage, air flow efficiency, sound, etc.
On the CS....have you take a look how the tubing is routed and the size? Can't be done on a street car so the only option is what ExMB mentions and wont be an easy feat given the space and requirements.
