Are you sure about that because the difference is large

due to gearing, torque and accelerative force at the contact patch

The demolition is large and round a track........................its not close because the corner exit speed difference magnifies the accelerative differences, so on a 1:30 type track your are looking at 6s difference between a well driven RS and a well driven 718 GT4

I agree track is no comparison. Rs will destroy almost anything thats not a full blown race car. Im talking for what 95% of people may see in street driving, which is not the intended purpose of the RS. But its interesting how close they are for a single pull until the numbers go really high. The RS costs double for a reason and its worth it.

Nowhere near that gap on most tracks I would say. Both cars on (non-R) Cup 2 tires my 718 GT4 was +3.5 seconds to the 991.2 RS on a very long 2m20+ track with a favorable layout for the 911. Manual GT4, too.

I estimate +2.5s on my local 1m55 track which has a slower and more technical infield section. On this track my 981 PDK on slicks was 1.5s faster than any 991 RS on cups even with its smaller 360 HP 3.4L engine. 3 seconds+ ahead now with the tuned 3.8L.

The gap is largest on the Nurburgring where you need both power and rear stability over the bumps, can't touch a 911 there.

Sure .......its not close

I really like the Cayman platform and own a 981 GTS and 991.2 GT3 RS ..............so I have no dog in this "fight"

When I say not close, I mean a vast gulf.........the reality is the GT4/Spyder doesn't have a lot of torque across the whole torque curve - its a major deficiency along with struts front and rear - the combination of the two has significant repercussions for overall performance. Thats the straight truth.

You are a long way off beam - just have a look at the track times.

No one thinks its close, honestly they don't. Its been proven at a gazillion club events around the world and no one uses the GT4 beyond that level.

PS I was inline for a GT4 - thinking Porsche would have upped the torque and gone to multilink at the rear plus PDK on release..................that never happened, cancelled my order. Very disappointed with a platform with so much to offer yet delivering so little (relative to expectations).

I don't want to rain on your parade but BS is just that BS - I'll butt out from here on in.

Ok this is with stock air filters BC Fabs inconel rear pipe only. This makes some power. About as fast as my 991.2 carrera T with stage 2 giac tune.

If you do precisely that you'll see nothing like 6s on a 1m30 lap. It's about half that. Which is considerable, but not a stupid amount.

What "level"? There's no competition between two different classes of road car. You drive whatever you want to drive (or what your ego is comfortable with) and all GT cars feel well at home on track. If you want competition nobody uses a GT3 RS either you get a clubsport or cup car etc. end of story. Road cars are not race cars.

In a club/amateur setting the performance differences between different drivers are a lot bigger than there is between the cars anyway.

Takes about 125Miles/200KM for ECU adaptation?

Clubsports are also considered a big disappointment - Cup cars are OK solely for track in specific but limited comp (although entertaining). Theres a whole world of motorsport out there whereby a car is only eligible if it was able to be road registered in the first instance........

You can blather all you like, but you are waaaaaay off beam and its easy to prove

Left time GT4 right RS

Nürburgring - 7:32.00 6:56.40

VIR - 2:50.31 2:41.60

Road Atlanta - 1:32.24 1:26.24

Assen - 2:00.11 1:49.23

Sachsenring - 1:31.51 1:26.39

Circuit de Nevers Magny-Cours GP - 1:54.95 1:50.36

Mendig AFB Circuit - 1:50.98 1:43.96

Circuit de Nevers Magny-Cours Club - 1:20.11 1:17.68

NCM Motorsports Park Grand Full - 2:13.21 2:04.34

Vairano Handling Course -1:13.95 1:11.73

Pretty much in line with what I have personally observed and attempted to convey to you.

Obviously you can believe what you want to believe.

Anyhow, I'll butt out and leave you to it. The numbers don't lie.

Hate to break it to you but a lot of fastestlaps.com data is garbage. First one I clicked on was a magazine testing readers' cars with them in the passenger seat.

A lot of the others have the RS on the Cup 2 R tire which completely skews the comparison.

But this is indeed a pointless argument - reminiscent of the average discussion in the YouTube comments section - and it would be nice to see some more on topic Dragy results.

lol a lot more relevant than anything you have put up - lol. Those were just obvious examples.

Take your car to a track and stop being a dick and racing on public roads.

Join a club and start doing it safely. Don’t be that Porsche driver that gives the rest of us a bad name.

Go to a track, get a race licence - compete - suggest you don’t do it in a spyder get a car that can support a FIA compliant cage.

Maybe you’ll learn something.

I know you’re trying to have fun but there are ways and means to achieve this.

Enjoy your spyder.

no reason to be upset, Spyder is made not for track, it’s made to go a bit faster than speed limit with open top and enjoy driving.
track is different story , it takes a lot of ***** to do it , there guys with old 911 going mind bending fast !!!!!!
i can not do it ☹️
RS is a different animal, I drove it and it blew my mind , there is no comparison to GT4 or Spyder , on the back roads it’s a pleasure to drive either one of them , it’s just Spyder or GT4 is easier to get to the limits vs RS you need a lot more road to find it’s limits
both cars are superior !!!!
enjoy all of them !!!!
