2018 GT2 RS takes the ring

It doesn't matter who is driving or what tires are on the car, an otherwise stock besides tires/brake 996TT X50 driven by a professional driver isn't going to keep close with a 997 GT2 driven by a professional driver around that track. You could give the 996TT Pirelli slicks, it isn't enough.

^ awesome vids. Kai makes it look easy in that first one. As a mediocre/not smooth driver, it's always surprising and fun to see how smooth some of the fast guys are.

Porsche has a tendency to clamp published Ring times on cars so they do not infringe on the advertising of newer cars. I have asked a friend at PCNA why Porsche never published Ring times for the X50 and was told that PAG was just fine with the 7:56 slot the non-X50 996 Turbo fell into and that an X50 time would "muddy the waters".
We could probably bench race this here for another 20 years, but then we'd have to change the name of the forum to "Corvette Forum"...

Porsche 911 Carrera S (991.2)...420 hp/368 lb-ft on Pirelli P Zero tires ran a 7:34. I assume this was a full lap and not BTG. I have no idea what either the 996 Turbo or 991.2 weighed at the start of the laps they did, and I have no idea if the 996 Turbo was a full lap of BTG. I do think the GT2RS's tires (Michelin Pilot Cup 2's) are likely better than the P Zero's the 991.2 used.

The 991 OEM chassis/suspension has a far superior lateral grip level than the OEM 996. They aren't even close in cornering performance. Cornering performance is everything in determining lap times.

Just a note...
It is said by people who know the track and have experience that R-compound tires alone make a 10 sec difference give or take, on the Nurburgring.
That’s 7:46 for a regular 996 Turbo, and id give the X50 a few more seconds down on that. On top of that, the track today is faster than it was before even when the 918 set its time. I’m with Dock on this one, and maybe not 7:30 but I’m sure it’ll do 7:3x.
991 chassis is far superior but weight is always a big factor and the 996 is much lighter.
Walter Rohl is a fast driver but not even close to the fastest of the Porsche drivers.

Some 991 models have rear wheel steering, the GT2 has it. Listed under chasis in the below reference.

The 991 chassis is light years ahead of the 996 in terms of maximum cornering speeds. There is no comparison. A stock 991.2 Carrera S will leave a stock 996TT for dead in the bends.
The weight advantage is with the 991.2 Carrera S as well. It weighs around 100kg less than a 996TT X50. 1445kg to 1545kg.
The best a 996TT X50 would do on modern street tires is in the mid to low 7:40s. Which is a fantastic time for a 15 year old car.

Most 991s here though are at 1550-1600 kg, and almost up to 1700 kg for the targa. That may vary from country to country however.
