The extra 150 HP of the GT2 RS was only good for 10 seconds over the .2 GT3 RS. These two cars compare pretty well otherwise. This comparison also eliminates track changes and improved tires.
not quite. Cup2 R on the .2 3RS vs N2 Cup2 on the 2RS. the extra power (and slightly different suspension I think) on the 2rs has to overcome a pretty hefty tyre disadvantage. Put the 2rs on the same Cup2 R and I reckon it'll be 6:40 if not less if Porsche bothered to go back.

Which pretty much still supports...tires. It’s probably 40% of the difference. Hey, that still leaves 60%! I am getting ready to change tires soon, so hoping to get the new tires from .2 GT3. Not that i will be able to notice the difference!
While it is obviously an amazing laptime, I think it's a real shame that they have used the Cup2 R tyre on the .2 3rs. Aside from the headline, personally I'd be far more interested to see what the impact of chassis changes are on the car rather than the simply due to a hotter tyre. In particular the .1 to .2 gt3 and rs, it would be far more informative to have used the same tyre imo.
Come on, seriously?! The name of the game is to post the fastest lap the manufacturer can; not to do an apples to apples comparison with less-than-best tires. This thread is a joke. I mean, why don't we go back and pull some tire technology from the 997 era so that we can get a fair comparison to those cars? (Yes i realize they were 19's; I'm just making a point).
People dont realize that if you put the same tires 997.2 GT3RS had on this car, it probably wouldnt even come close to the base GT3. Tires play a huge role.
I couldn't agree more. This was definitely a more ***** to the wall lap that I'm use to seeing. Estre is lifting wheels in many corners, in a rear engine car with a resurfaced, cut and smoother Nordschliefe. That is as aggressive as I've seen in a street car, prove me wrong.

Yes seriously. People are claiming the car is a monstrous improvement over the gen1 - it is but only on the right tyre. Which therefore doesn't exactly apply if the old car fits the same tyre. I don't have the .1 rs and I can't get the gen2 even if I wanted so I don't really have a dog in this fight in trying to proclaim the .1 being as good or not.
And yes to be honest I'd love Porsche to get some N1 Cup2s to replace the current N0 for the 997 gt3 rs with the same compound as the 'standard' N2 gt2rs/gt3rs and run the 997s (all gen) to see exactly how much difference the old to new is given all the improvements (e-diff, rear wheel steer, extra downforce etc) That's more interesting to see what the chassis changes over time have made than simply having a stickier tyre to get a headline grabbing time surely?
All i can think about when watching that lap is how out of the (guess) 4,000 units of the 991.2 RS they will make literally no one who buys it will ever come close to that lap. Pro drivers are pros for a reason. Impressvie
I'd sugest that a dedicated non-pro driver would do the same time but Bridge to Gantry (which is aprox 20 seconds shorter).
That is definitely within the reach for us mortals.
You "just" need to do your homework - practice a lot.
did anyone notice the speed differential by the bridge between the .2 GT3 and .GT3 RS, despite of the RS getting a higher exit speed onto the main straight? It shows how strong the 991.2 GT3 is, and with better tires, the .2 GT3 would have run an even higher speed and plenty lower lap time.

I was waiting for someone else to notice that... on most straights, the GT3 (.2) and the RS were almost identical... which again, really shows the power of these motors. And the GT3 while admittedly a bit less aero, it also has way less grippier tires!

..... or maybe it's just that the RS has a lot of drag due to the extra aero which shows primarily at the very high speeds?

The 3 RS maxed out around the 280klm they most certainly had the rear wing at maximum attack angle ,,,only with other aero changes the drag has increased ,,,,the obvious factor with the GT2 RS max speed is the extra power and torque it has to over come the drag issue ..

The difference in aero is bigger than the difference in tires at higher speed (certain even without seeing those tires). Getting more than 10% extra grip on top of MPSC2 N1 is nearly impossible on a street legal tire - even Trofeos that are hoosiers with minimal tread do not give that. 10% extra grip via aero means extra 310lbs of aero. At high speeds RS has more than that on top of what GT3 has. At low speeds, tires may be more beneficial. Aero is a huge deal in general - just look at the Viper ACR or Radicals.
The Cup 2 R is a big question mark - are they two-session cheaters, like the Huracan Perfomante tires, one-day wonders, like the Corvette tires or something more durable? AP made a sniping remark about Perfomante tires, saying that the new RS tires will last about as much as regular MPSC2 on track, unlike the bespoke one-session tires some other manufacturers use for their Ring records. But that's something I take with a grain of salt. We'll see soon.
