991.2 GT3 RS suspension for Nordschleife
Discussion
I drove a standard GT3 RS WP with the Manthey geo on the Ring a few weeks ago. It was sensational - turn in was outstanding and much improved over OEM; the steering is lighter and overall the set up liberates the fantastic chassis.
I also have a GT2RS and have recently had the Manthey KW suspension fitted, along with full geo. It was extraordinary. The suspension is derived from the GT3 R race car - and it shows. Whilst stiffer the damping quality is in another league to stock. On the road of course the car is slightly compromised (but not badly); but on the Ring it was sensational.
A set up is of course not a big outlay, whilst the suspension kit is. The former make a big difference; the latter takes the car to another level!
Hope that helps.
Cheers

Have you spent much time there on the standard setup? Notwithstanding stefan’s post the standard cars are already pretty optimised!
Forgive me as I know the question wasn’t aimed at me, but I do agree, the OEM set up is excellent. I’ve driven scores of laps in my previous 991 RSs there at enjoyed every moment. That said, having driven my friend’s RS a month ago with the Manthey geo, I will definitely be booking mine in next May when - hopefully - I will back at the Ring with DN events. It was that good.Oem always going to be lacking on track.
Geo's a must have , and then really caster pucks and better pads.
As for shocks, my self I would go Ohlins TTX.
Being 2 ways you can get your head round fine tuning as a ring setups way off a smooth track set up.
The new manthey kW are 4 way dampers.
So very tricky then to setup on your own.

Nice to hear from real experience.Many many thanks for your great reply’s.
Stefan S experiences certainly helped me and I’m planning KW coilovers for the next season.
My very experienced friend and VLN driver is very happy with the KW coilovers on his personal 991.1.
However is the 991.2 oem so much better and KW coilovers not really
necessary ?
To answer the question I have 1000 plus laps over the last 12 years but new to the GT3 RS world and has done about 50 laps this fall in the RS.
I used to drive a rebuilt E46M3 with KW Clubsport 3 set up by Raeder/Manthey.
With that experience I fell my 991.2 GT3 RS is way to soft , sloppy and unstable with the standard oem and no Manthey set up especially going down turning right at the 2km sign entering the Hatzenbach area, fuchsrohre , downhill after Kallenhard and uphill after bergwerk. However can see the previous owner has done some setup. Front camber is all inward and the rear wing is fully down.

I do agree on the Ohlins option, I would add Schirmer Nitrons that they developed for the gt3 rs, Motion Control as the absolute best, but Manthey KW BY FAR are the most practical, for one lift can be integrated, second their damper spring is better, more compliant and the exact rigidity needed and to finish it up, they can provide you the correct settings for various driving scenarios, basically with Manthey you will not have to go around trying different spring rates or try to find how to setup for road or track, or for mountain sport driving.

Given your experience level I would say go straight for the damper upgrade, RSS top mounts and geo. IMO it's still not enough though. You can't hide the weight of the car. i ended up buying a cup car and that solved the problem! Stefan S experiences certainly helped me and I’m planning KW coilovers for the next season.

Once you understand differences between the low speed and high speed components of compression and rebound, and provided you have some parameters to work to, they are not too bad.So very tricky then to setup on your own.
Been running 4-way air shocks on downhill and enduro mtbs for years now. (That there's a £500 rear shock.)
Setting up from scratch, with no advised spring rates or settings would be tricky, but not completely impossible. IME (limited), bikes or cars, there's only a relatively small window of settings which actually work with any given spring rate.

what's a cup car weigh >1200kg's ? so not much saving and now just hassle getting it to a track !Porsche911R said:

250ish kilos lighter than a 991 RS . That's quite a saving - you really do post some drivel R.
Why drivel, it’s not light ! One would think it were 900kg when people say how light it is. Bac mono is light as an example at 540kg not a bloody cup car lol.

Not sure whats trying to be achieved as the rs out the box is wicked,but as said you can never hide the weight, they do feel even heavier as you are traveling faster the brakes having to work harder.
Maybe a road converted cup car is the way forward,lightweight,steel brakes and tyre selection.

250kgs is massive amount out of a car like for like on track
It’s not 250kg though ! That’s been made up for effect.And thus you still get through pads and disks etc esp if you are going faster.
And yes any wight savings is great, but a cup cars not a light track car, it’s about the same as my 987.2 Spyder in fact !
To be fair, when compared to a steel bodied gt racing car a cup is pretty light. It would be comparing apples with oranges to compare weights of gt racing cars with any other racing category.
Cups have always been circa 200 plus kg lighter that the RS road version. Those weight savings help create a fundamentally improved performance window.
