Even with its NA motor the .2 3RS is throwing down seriously fast times at various tracks including faster times or equivalent times to/than the 918, Perfomante, 720s, 675LT, 488, ZR1. That to me is actually more impressive than doing it with 700hp. TT 700hp makes it easy. Everyone gets blinded by the 700hp.

The 3RS is doing more with less. That’s more impressive to me.
Laguna is not all that tight. And there is almost no chance the dot 2 3RS is either faster or within a second. The Laguna lap for the 2rs will be out in 2-3 weeks. Will probably be very late this year or early next year before a time is set on the 3RS.

P.S. Why not try the dsc module? The dampers at least can be solved. And what's wrong with the spring rates? They are plenty hard but enough to give decent compliance.
i don’t have alignment, I have the full Manthey 3-way KW Competition set-up fitted, with optimised settings, for the very reason that the alignment doesn’t do much, (Manthey will tell you that all they can do with alignment is to stop the arch liners rubbing through).
Having said that, even with KW kit, I still went through the liners first day out at Zandvoort,

It’s very very good kit, compliant on the road and dials out a lot of the issues on track. Only small downside is that it squeaks a bit, but you don’t notice that when going fast!

i would still have it stiffer, inc replacing the sway bars, but they don’t recommend that as too compromised on road. Fine with me, as it’s not for racing -just wanted it to the stage you can really push without it falling over on itself and oversteering into the undergrowth.

FWIW, the Manthey 2RS set-up on the 2RS uses different spring rates, packers and settings than on the 3RS, even on same KWs. Shows they handle differently.

It's counter intuitive to suggest that an alignment isn't beneficial for anyone anywhere. Driving styles, track surfaces and even car tolerances are different. Without taking Pyrometer readings from and individual car on an individual track, I don't see how one could say optimising an alignment isn't beneficial at all. I'm not sure what the adjustment range is on the 991's though, but that seems far fetched at best.

If you compare lap times on Fastestlaps the 3RS is within a second or so on the shorter circuits.

It was also estimated the actual time difference between a .1RS and .2 3RS at the Ring was about 10 second Which translates into about a second or two on shorter American circuits. That’s the same delta at the Ring which separates the GT2RS and .2 3RS

This indicates to me that with the 2RS’s 180 hp advantage over the 3RS the 3RS is the better balanced more effective track weapon which seems to do a lot more with a lot less.

For curiosity I went out check Fastest Laps and the closest delta is 1.6 seconds on hockenheim short which is barely over a 1 minute lap. Essentially 2 seconds at Sachenring (1.98 seconds) where it beat the 918 and set the lap record.and 3.5 seconds at Variano which is also a very short lap.

Not sure how you came to that conclusion. The dot 2 3RS may be slightly better balanced, but not enough to negate the sheer brutality that the 2RS will bring to the track.

My point is very simply is that the GT3RS although being 180 hp down on the GT2RS is quite close on some shorter circuits to the 2RS times. Playing at almost 200 hp down and looking at these times clearly indicates to me that the 3RS is the better balanced track weapon that requires 180hp to overcome for the GT2RS.

Speaks volumes as to the .2 3RS’s capability.

Bought a track car as a newbie to go to Sebring in 2003, first Porsche was 997GT3 came in 2008.
That video was watched and analyzed as part of my education haha..

I've seen quite a few reports of the Gen V ACR being quicker than the 996/997 Cup cars, so I'd be pretty surprised if the 2RS doesn't give the new Cup car a run for its money.

The ACR is not quicker than a 7 Cup. Its probably quicker than a 6 cup on most tracks on slicks. The ZR1 could be quicker on slicks, but only if the weather is cool as the C7's seem to pull timing in hot conditions and power suffers greatly.

Any word if this is going to be the homolgation special for the new dual chamber cylinder head?

The engine is the exact same one from the GT2RS street car and so is the gearbox. Just like how the GT4 ClubSport is.
