How much weight savings is there in a carbon tub?
If the 992 GT3RS had a carbon tub, how much weight do you think could be saved?
If McLaren can do it in a $180k 570, why cant Porsche?

Well … one of those companies is profitable and one is not.

911, 2600 lbs, 550 hp 4.2l NA ICE, $600k, I’ll bite; manual or not. But must have aggressive PDK software like the “ralley mode” of the Dakar. Haven’t driven the 3RS yet, arrives next month.

pretty close to what I'm hoping to accomplish with my project car / S/T clone. It will have S/T fenders, doors, roof, but PDK and 4.5L Deman NA engine w/ 600 hp . . . it will also have RWS, but looking to incorporate some of the RS suspension components - not quite sure how much of that is possible. I have a set of Manthay LW wheels on order, and P101LWs - those should be pretty close to the mag S/T wheels, but also will save some weight by deleting the motorized spoiler, and with the full Akropovic exhaust. I plan on full Resonix sound deadening, so that will add 30+ lbs back. Overall, I hope to have a PDK S/T that weighs close to the same, but with RWS, better sound deadening, and some of the comfort features I've been working on - not to mention 600+ NA HP!

Mclaren CF monocoque tub saves around 210lbs . Significant weight loss but not as significant as you might expect.
Much more weight savings in a full carbon monocoque such an Enzo or Mclaren F1, but also dramatically more expensive to produce.
And even just the carbon tub of the Mclaren is still much more expensive than a standard lightweight sports car frame.

Mine is the 10th post on this thread, yet seems like no one tried to answer your actual question so I will.

Don’t forget about the structure rigidity. Carbon tub is at least 100% stiffer than the chassis in a GT3.
Bugatti Chiron is at 65000nm. 918 chassis is 48000nm. A typical GT GT chassis is in the 25000nm range.

got the S/T roof, and a 2nd set of fenders, but no RT doors yet. . .
