So it seems that AP wasn't lying as the 992 engine is "different" and that he was referring to the 991 GT3 engine when it said the engine wouldn't fit. There you have it.
Also, someone in Italy got the 991 lump to fit in a Cayman, but with great, great level of effort. I believe they documented on Instagram/Reddit, or other similar platform.

Where do you see the glass?

Probably not. But it is certainly unethical marketing for Porsche to represent their recent GT4RS Nuremberg lap time as if it were a production street car if it was not. And I think we can all agree that tires in particular play an outsized factor in the overall performance of any vehicle - Tire choice can dramatically improve braking, acceleration, and cornering simultaneously.

My .02 as a previous 981 GT4 owner and current 718 GT4 owner..

1. Yes, the car is still held back with the tire sizing vs a GT3.
2. I like the look personally, form follows function but still an eye for appearance.
3. I think it looks cleaner without the WP.
4. Intake scoops and sound are mega. Hopefully the GT4 cat back exhausts will fit and an OPF deleted, merged flat six wail can be had.
5. Not looking forward to centerlocks or 20" track tires/wheels.
6. 40K is a bit hit over a GT4, and closer to a GT3. But it's really only a 30K hit since LWB and PDK are included, 27K if the rumored 3% GT4 price increase is true. 27K for the content over a GT4 is a freaking steal in my opinion.

Summary: They put the GT3 engine and close ratio PDK transmission in an already fantastic car. TAKE. MY. MONEY.

It looked like there was glass in some of photos and was verbally described in one of the magazine articles.

Standard equipment also lists Navigation, Apple CarPlay and Dual Zone A/C … so even better.

Agree, lots of value included here.

You will be able to buy a C8 Z06 with a Z07 package that will have the CF wheels, Cup2R tires, and everything else you see in any car showings/lap time record attempts/etc. What you see is what you can get. None of this "you have to wait 13 months to get magnesium wheels" and "Cup2R" tires are 2+ years out (it did take 2 years for people to be able to buy them in the US after the 2017 GT3RS nurburgring lap time).

There is probably a reason why Cup2Rs cant be sold with the car from the factory in Stuttgart. Its probably a similar reason why new GT3s now have "track brake pads" that you must purchase because "street pads" fall apart in the track. Its a bit dishonest.

I simply cant buy their car here. You can buy the Z06 or ZR1 as chevy used in their VIR or other official record break attempt videos.

Ok so the same tired argument that's been happening for years. I view tires as a non-issue. They are a consumable and I don't consider them "part of the car". You want Cup 2 R tires? Put them on. Not a big deal and other car companies are free to use whatever tires they want for testing and setting lap times. Now... if the tires are not street legal, that's another story. Is this all an ethical dilemma? I don't think so. But y'all are free to disagree.

Using a racing bucket seat with a halo is also a non-issue for me because that's a safety thing, especially for a racing driver setting an all-out lap time. If I were a driver I would absolutely refuse to do my job with an OEM seat in the name of safety.

Radio and AC delete? Maybe that one holds more water. But just take the radio out when you get the car.

It may be a little in a gray area, but it doesn't offend me. Porsche worked closely with Michelin to develop R tires specifically for the GT4 RS (they are not off the shelf - special N-rated tires made for this car only). Yes, you have to buy them separately from the car but that's not a big deal to me.

The "configurator" is not always up to date, nor working correctly, but aside from that, given that I "still" haven't been able to get PS4S since April, may be the other reason its not readily up for order.

I'm interested also. Either it will have the same manual gearbox as the GT4 (where the torque curve will have to be further compromised to meet the 310 ft-lbs limit of the gearbox) or they will have to strengthen the box (or take the financial risk of exceeding its limits). Or they will have to use a new manual box (seems unlikely for a small number of cars).

I don't know. But AP said Porsche does not have a manual gearbox that mates with the GT3 engine that will fit in the GT4.
