Key secret why 991.2 GT3 RS will post some great lap times

On Algarve(around a 2 minute track), the RS was 6 seconds faster than the 991 gt3. Again it's redundant. I only know that the 991.2 gt3 is way faster than the numbers would ever suggest and that on suspension and torque Porsche made it faster than the 1.rs pretty much everywhere.
The RS is a gt3, plus a lot more.

Zactly. Same torque and hp at 600 rpm sooner is an incremental change. Not a huge change by any stretch of the imagination. A step on but incremental. Stiffer spring rates make for less sway but less forgiving on certain tracks that are not smooth and certainly less optimal for street use on your average Sunday roads.
.1RS clearly capable of replicating the 7:12 at the Ring the .2GT3 hit. (The old 7:20 Ring time is not representative based on poor weather and yestersdays tires) .1RS has same hp, same springs and dampers as .2GT3. In fact .1RS has wider track and better aero. The new .2GT3RS with an additional 20 hp and stiffer spring rates (likely 15 at rear wheel) will be able to bite off another 10 seconds over a 7 mile run at the Ring especially with the better tires. No doubt. Time differences less on shorter tracks and cars are still close enough main difference will still be dependent on drivers especially where .1RS has updated rubber shoes.
The GT2RS nailed a 6:47 at the Ring with over 700 hp. My bet is the .2GT3RS comes in around 7:05 to 7:00. Manthey .1RS hit 7:09 without any headers.
Also can someone point me to where the .2GT3RS has rose jointed control arms????? Its not in the PAG materials nor did AP mention it which he would be crowing about if it had it. That's a GT2RS goodie not available on the 3RS.
Wagers on Ring times?

Your insecurity is showing.

You're sure about quite a lot...
It's in the press materials. It's also on the Porsche.com website under technical data:
Front axle Lightweight spring strut axle (McPherson type), all suspension mountings ball-jointed
Rear axle Lightweight multi-link suspension with wheels independently suspended on five links, all suspension mountings ball-jointed
They completely reworked the GT2's suspension to help it put down 550 lbs ft and 700 hp through the rear wheels. Ball joints all around, different spring and damper philosophy, etc. They then evolved the GT3's suspension from that using many of those parts including the rose-jointed mountings. This has been mentioned quite a lot around here?

Hell, even my stock 997.2 GT3 put down 366whp at 6600 rpm. Where are you getting your numbers from?

That’s a MAHA dyno, which read very conservative since it’s automatically assuming a 25% drivetrain loss which would not be correct for GT3s.

MAHA is supposed to be very accurate at measuring crank HP, but not always wheel HP due to many different variables and formulas. Believe what you want, doesn’t matter to me, but I know that MAHA graph is not accurate.

they measure the losses, the measured losses are added to the WHP to deliver the crank HP. Its pretty straight forward. Reality is better than fantasy.

Porsche press kit listed it at 7kg. 20-30kg would be ridiculous. It's a tiny air pump that lifts the car by an inch only. All 4 air springs on a cayenne are less than 30kg, and they lift a heavy truck by much more, and there are 4 of them.

Regarding seats - I meant just seats without rails or lifts because those would be the same on wither buckets or 4-way sofas. No way there is 15kg difference per seat given that the railing mechanisms are the same and the difference is just frame and cushions, which are very light in either case. This photo makes little sense because it shows bucket seat with rails and some other seat that does not come in a GT3 in the first place - what can it tell us?
