.2GT3RS driving impressions vs .1GT3RS

Might do a side by side vid with cars synced at the start of their fastest laps later in the week.
I'm glad there was track sanctioned timing available. Racechrono paired to a 10Hz bluetooth GPS works most of the time and usually matches the official times to 0.05 of a second but sometimes it just stops working for no apparent reason.
Not sure why. When I started using it the GPS refresh was a solid 10Hz and these days it fluctuates in the 5-9 Hz area.

Nice videos and driving greenhorn.
No question .2 RS has a little more power and juicer torque curve, but also no question that .1 RS was woefully undersprung from the factory; this was flagged early on by anyone driving it properly on track.
I’d be interested to see how the .2 RS compares at Spa vs a Manthey .1 RS as this would largely negate suspension differences and yield a truer reading of differences in respective power units.
Nice to see a proper RL discussion for a change....

I just managed to find the video footage of the fastest .2 GT3RS at the Spa event I attended.
2:36.4 on Pirellis with traffic
After looking at that I think that Cup2Rs can get this car down into the 2:33-2:34 region. Unbelievable.

I just did a trackday on a local small track where I am quite fast
I was doing around 1.25.2 best lap with the 991.1 GT3 with Manthey set up and trofeo tyres
With the 991.2 GT3 RS with the aero set for track and MPSC2R tyres I did a best lap at 1.22.6
So yes the new RS is really fast

Disclaimer: everything below refers to on track performance, if you don’t plan on tracking, either of the cars is amazing and will give you plenty of joy on the road.
I recently managed to drive both .1 RS and .2 RS over two sunny days at Spa.
My initial impressions from driving the cars at Hungaroring (posted earlier in this thread) were amplified to a surprising degree.
I arrived planning to get the .1RS below 2:40.
Before I managed to warm myself up over a couple of sessions in heavy morning traffic I saw a .2 RS post a 2:36.5…
Impossible I thought. Not even on fresh trofeos. He must have gone straight through Eau Rouge.
I anticipated to see the .2 RSs dip into the 2:38s but not 2:36.
That is GT2 territory. With Manthey setups, pro drivers and stuff.
Managed a 2:40.9 in the .1 RS before lunch (on Cup2s).
Thought I could get it in the 2:39s in cool afternoon air without traffic but it became obvious that the .2 RSs are out of reach in terms of ultimate pace. Another .2RS driver posted a low 2:37.
Being lucky enough to be able to do so I decided to see for myself what the fuss was all about. So I jumped into the dunlop equipped .2 RS.
First session,
First hot lap 2:39.0
Second hot lap straight after that 2:37.7…
Drove slowly back to the pits, checked the monitor displaying official timing – 2:37.7
That was on the same tires I used in Hungary – they already had about 2 days of hard running in them and another two days of slower pace driving.
Wing in low downforce position, no alignment, no corner weights. Car was as delivered off the showroom floor.
Spent the second day trying to see if I can catch up to the fastest guys. Traffic was an issue. Ran patiently all day trying not to ruin my tires.
Once traffic cleared after 4PM, I managed to do 3 laps within a tenth of a second around the 2:37 mark.
Two last laps were very high 2:36s.
None of them were perfect. Combined best sectors in racechrono show a theoretical best of 2:36.11… on used dunlops
Now, where do the four seconds come from?
This time around I noticed the difference in stiffness between the cars. The stiffer springs of the .2 keep the car planted at all times, most significantly when you mess up in a corner and want to make a minor correction be it with the brake, throttle or steering.
In the .1 RS any movements once the car is set in a corner result in either oversteer or understeer. The weight transfer on the softly sprung car is too significant.
The .2RS masked my sloppy driving.
Traction control intrusions, once they happen, are more nuanced and subtle. For the first time I thought I could gain some time by switching traction control off.
In the La Source hairpin and bus stop chicane before that I think I could have managed the slight exit oversteer myself. But that would be true for both cars. All the other 120mph+ corners contained my bravery and TC stayed ON at all times.
Straightline speed is very similar, so don’t think much time is made there.
Stability braking into a corner, room for small corrections once in a corner and fast exit are where it’s at.
Shifts are faster, but again it’s not where all the time is gained.
I see myself doing a 2:36.5 in perfect conditions. I don’t see why a competent driver with fresh sticky rubber and clear air couldn’t do a 2:35.
If you’re after laptimes, the two cars are worlds apart.
I’m not sure Porsche intended for the .2GT3RS to be that good

Great info - I have generally being finding 2s a minute difference between the two and secondly the front end on the .2RS is significantly improved.
Agreed, surprisingly little difference in the dry. The later versions seem far better in the wet.

Old post, just re-read it and it’s spot on.
I also drove .1RS bone stock at Spa @ 2:40 in 2015 and .2RS bone stock 2:36 in 2019.
Its exactly like that.
Because we had to my been to Spa once when we got there with the .2RS so I only had the muscle memory from 2015.
As soon as we @911rox did a few laps we knew going through the second half of Pouhon? flat after braking into the first half..
Doing the same tracks the .2RS simply eliminates a few corners or can take a gear higher.
Even before I got the .2RS, I had .1RS with adjustable KW MR on it and what struck me was the adjustability of the line or rotation of the car with the suffer platform. OEM .1RS is a bit more like sailing, once you have turn in, there wasn’t much adjusting possible.
I think the .2RS is perfect, almost too perfect.
Never drove a car so nice out of the box, you don’t have to be very advanced to play with the car and balance it through corners.
If you drove a .2RS for an entire day and finished doing a few laps in a .1RS or GT2RS you would feel how good the .2RS is.
Never mind the 997 4.0 clunky old 911 feeling like a 964 still.
Now I’m very curious what the GT4RS will be like with that kind of advanced setup and the same TQ in less weight..

Why GT4 RS if 991.2 RS exists? 
Never ever comparable.
