Love the comparo - and maybe I understand the goal, but if the goal is to truly compare car to car, to compare G2RS to Cup car, then why not run them on the same rubber? wouldnt that give you (and us) a true comparison for each cars capabilities if on equal rubber?
Just a thought. If i had a gt2rs (and I wish I did/could), I'd track it on hoosier R7's.... best level of grip balanced with longevity.

Without wanting to cause you any more headaches...
The Tropheo R is apparently slightly better than a Cup2, but not as good as a CupR.
I had to replace a set least week (nail..), and my car was at Manthey at the time. Like everyone else, they don't have Cup R stock yet, or I would have fitted to try. I asked if I should go with Tropheo, which they do supply, but they recommended sticking with Cup2 as Pirelli not much faster, not as good in the rain, and also has a tendency to move on the rim, requiring rebalancing.

Just received confirmation from Frisby Tires that we will have Pirelli's for both cars. While I know many will have comments, we are going with the best we can. You can +/- time after the test on what you believe is the difference.

Foot soldier, or other locals near Spa;
Would it be fair to say a well driven, but not pro driven stock GT3RS goes 2:40?
Then a GT2RS on R, should go faster then 5 seconds faster? Even on a hot day?
No?
I would think a GT2RS or R is much more then 5 seconds faster then a GT3RS on just MPSC2..

Or will the Cup be on some sort of race tire, while the RS on some sort of (sticky) street tire?

Looking to finalize logistics for event. Many thanks to David Murry, Road America, Pirelli, The Exchange and of course Bryan Sellers for helping gt this done. Now we can see how this car does on a track many of us are familiar with and against a car we know. May the best car win!!

Big thank you to Pirelli and Frisby tire for their support in this challenge. Trofeo R tires delivered and Slicks ready for Cup Car. Cars will be set up and ready for challenge. 650 miles on GT2RS in two weekends!! Break-in almost complete!

Push on Steve, it’s too good not to make happen.
Pretty crappy on Michelin’s part to not have Tires available months after Tires are used to set the Ring lap time.
Not cool. And stupid because this should be great marketing for the price of a set of Tires.
They gave me a set of tires for the Sebring shoot..
Pirelli isn’t the preferred tire but OK..
Understood on the lap times. They are just references to anticipate the Delta between the two.

The VBOX would be the way to go, as that is what Porsche used for the ‘Ring laps of the GT2RS, the 919 and the 991.2 GT3RS. We used it at VIR for C+D Lightning laps for the latter two. Nizers video is the VBOX HD2 from Hockenheim.
If y’all were closer,I’d supply the equipment for the test. That would be fun.

We got to have VBOX there.
you can use my Fedex acc# :-)
Lets make it happen!!
Im sure the driver will be interested to see his Delta time go up and down on the Racelogic display.
The UK boys should send you a ticket to go set it all up.
THIS WILL GO VIRAL.

Second that for VBox in both cars! This comparo may well become as one of the best vids of the 991 generation...

This is brilliant - a fun comparison and thanks for putting it on.
FYI in case you haven’t used them. Trofeo R are really good semi clicks - I use them back to back with same driver on same day with Pirelli slicks at Bathurst in Australia. Car is modded 997.1 GT3. Did 2m 27s laps on trofeo R at 29 psi hot. Good at that pressure. No more. Then did 2 min 25s, with a little left in, it on new H compound Pirelli slicks.
One tip, I find the trofeo r are not good on their first heat cycle. Really slippery and average. Multiple sets have been the same. Then they cool, then the second session on and awesome.
