Not very since what they really ought to do is produce such a setup for the rear. Unlike with the 911, making the front end better really wouldn't help much as the limitation is at the other end.
This! They need to address the rear end first. The front suspension is quite good as is.
Notice the differences in the weight transfer between the GT4 RS and the 992 GT3 between the 4:04 to 4:11 mark in the video: Some of that is due to the differences in spring rates/suspension geometry as well as difference in roll centers due to the wider track width of the 992 GT3 as well as the rear 21 inch wheel on the 992 GT3. The 992 GT3 looks planted relative to the GT4 RS.

If the latest speculation on Motor1 is anywhere close to the truth.
500hp at 130k doesn't sound right at all. I think there is about 0% chance they give it 85hp more than the GT4 and essentially the same power as the 992 GT3. At that price and that spec, they would never be able to make enough of them.

Agree. I really don't see how Porsche is going to pull 85hp without going turbo or turning the engine into a 4.5L or larger. I'm still holding firm on 425 to maybe 450hp with ECU and titanium exhaust and maybe some other trickery. Even with the ram air on the rear window, I don't see how that is going to add 85hp. The performance gain will be mainly from weight lost and improved aero.

I think it's more of a matter that Porsche wouldn't let the GT4 (even RS) have better performance than the GT3. There's a graph on this forum that shows that Porsche is pretty good at price/performance where most cars line up nicely with the exception that GT cars are above the line, but within the GT range, they still fall into their own line. Also, so such a big horsepower jump from "base" GT to the RS is completely uncharacteristic of Porsche where the horsepower bump is usually minor and what you're paying for is suspension, aero, and exclusivity.
I would hope the car comes with a multi-link rear suspension (wishful thinking? maybe not)
I'll take the over on the 450 hp
I'll take the over on the pricing as well
will it have 500 hp? I don't think so
will it have 470 - 480 hp? we've already been told that it will
most of you view this as the typical iterative model release
I view it more as bigger bang for the buck, end-of-the-line, NA motor, let's see what EV looks like in sports cars as the next iteration of the Boxster/Cayman production
should be getting closer to unveiling, hence more "timed" leaks, closer to actual numbers
typical magazine hyperbole to round up from 475 hp to say the car will come with near 500 hp
some of us will be correct, some of us won't (will know soon enough)

Doesn't the current GT4 already out perform the 997 GT3?
The 992 GT3 is a monster. Even with the same power this new GT4RS likely won't keep up with it when the GT3 has so much more aero, better suspension, wider tires, and RWS. So I don't think this is an issue. And as long as the price isn't much lower and the availability is limited, this will all be fine.
If they did nothing but drop the multilink in the rear and the new 992 GT3 front end under it and left everything else alone it would be a win for anyone buying one. Not likely to happen but...speculation is fun.

The 997 is several generations older. I don't think Porsche would allow the GT4RS to out perform even the 991.2 GT3

Given the same power and the limitations in the chassis, even with same or better aero I don't think it will. And if it's very close... that's perfectly fine. It still won't be so close to the GT3RS and as there's never been a GT4RS before, having that level of performance as the swan song for the 981/982 generation seems perfectly fine to me. The price will likely be close to what the 991.2 GT3 was too.

RL is a bubble....we are not 100% of the GT market. Overall numbers are what the typical buyer will see and you can't have overlapping numbers between a GT4 and a GT3.

They wouldn't get that much power out of the 4.0 without serious mods, looking at the long history of 911 GT3 RS models they generally don't bump power much and there isn't that much difference with the regular GT3 engine. The RS adds more track focus but not a heap more HP.
So I doubt it will have above 450 PS. It just wouldn't make sense. It's true that the aftermarket is having a ball extracting more power from the 9A2 Evo but the first step for that is ditch all the restrictions Porsche had to put in for regulatory reasons. Needless to say, they'll have a harder time getting much more power with all the bits on it that make it legal to sell.
One way to do it would be to put the GT3 engine in it. In which case I'd entertain the idea of ADM
Hey... one can dream.
I'll put my money on 435-445 hp, more aero (already seen on the mules), PDK only, better suspension bits, some kind of fancy CAI from the rear quarter windows, and I'll get laughed out of every dealership I hit inquiring about allocations.

Not only that but PAG is also concerned about reliability and warranty which the aftermarket is not.
