@TDT - when are you on track next?
Silverstone on the 2nd (GoldTrack) or 9th October (Silverstone Direct) - Pending confirmation from some others - but will book one or the other early next week.Then my schedule is...
- PCGB @ Goodwood 12th October - Booked
- PCGB @ Castle Combe 18th October - Tentative.
- PCGB @ Oulton Park - 31st October.
I'd really like to get on @ Silverstone before the others, which are a bit tight, twisty and hairy, to feel out the new set up without too much risk - Silverstone is fast - but big and safe will plenty of run off.

Yep you should be ok at Silverstone, there are no hard bends anymore, it being a F1 track, Then my schedule is...
- PCGB @ Goodwood 12th October - Booked

- PCGB @ Oulton Park - 31st October.

The others I would be putting that rear bar back to middle lol

Kit fitted and setup done by Centre Gravity.
Massive improvement with front end grip but the real proof will be how it performs on track. Blyton Park booked for Sunday.
Nice, can you provide any further details of the setup? What have you done with camber, track via shims, anti-roll bars? Massive improvement with front end grip but the real proof will be how it performs on track. Blyton Park booked for Sunday.
What did they say about the kit?, did you have any other parts fitted?

Front: -3deg camber +36mm trackWhat did they say about the kit?, did you have any other parts fitted?
Rear: -2deg camber +12mm track
Left arb's in mid/mid
Largely positive feedback on the kit. The only negative is the rear adjustable toe links. Due to the thread, they are awkward to adjust.
Only the Manthey kit was fitted but the DSC unit was recommended as something to try before moving to new suspension.
Feedback from Blyton on Sunday:
- Temps were down from the previous trackday at Blyton by @6/7degC + cold wind. Lots of cars on the track as well.
- Achieved a 1:15.300 last time.
- Down to 1:14.113 over a single lap. Theoretical best was 1:13.250.
- Next thing is to sort out the amount of body roll (too much) before Croft on the 20th Oct.

Sounds good - Is understeer fixed for you then? - what tyre pressures did you stabilise on?- Temps were down from the previous trackday at Blyton by @6/7degC + cold wind. Lots of cars on the track as well.

What option you thinking about for roll control?.... Looks like the DSC might the best option whilst maintaining the OEM PASM dampers.
I think i will eventually end up with this unit also.
I had an interesting day @ Silverstone on Tuesday. Had some good running - only my second time @Silverstone - so I am very much still learning even which way the circuit goes. Mainly struggle with confidence through Abbey and Copse - as they are fast and blind so i lose loads of time there and am not using the grip or limit of the car through these turns.
How did the car feel with the new kit?... really good.
After a few laps at speed - i got comfortable with the ARB in full stiff... i.e. i didn't feel nervous and had no issues with braking - felt like the car was telegraphing its intentions a bit more immediately - so i felt like i could read the weight transfer and any hint of rotation better.
The front end was brilliant - my only issue being that i didn't quite manage my tyre pressures well enough so i was .1 or 2 bar over my ideal once I was up to temp and pushing on my best laps. I would still be interested in seeing what the new geo is like with the rear ARB back in medium though for comparision.
I was also testing out my new VBOX sport data-logger.. i had it paired to iPhone and the Porsche Track Precision App (PTPA) for more accurate GPS - (20hz vs 1hz) - good thing is that the VBOX is also always logging to its SD card so i can compare what the app says vs what just the pure VBOX says - plus i get all the additional vehicle info and video from the PTPA.

Tyre pressures - tried to keep to 32psi all around as under that, the sidewalls felt they were flexing a lot.
Due to the lowish temps, it was taking 7-8 laps to get the pressures/temps up.
I've asked CoG to price up a DSC v3 box as that is supposed to do a great job in minimising roll.
Looking at going to Croft on the 20th so will try the rear arb at full stiffness and see if that makes much of a difference.

I'm at the PCGB Oulton day at the end of this month.
'Very happy with the mods on my car ... and always happy giving passenger rides ...
Regrading tyre pressures ... I run up to 32 psi hot ... I'm looking for 30psi all round after a couple of cooling down laps ... and find the car goes quite loose at around 34psi ...

Hello!
I am wandering if someone has prices on the parts/kit, and more specific info on what parts/part numbers?
So I can buy them at a Porsche dealer without involving Manthey, and perhaps not buy the whole kit.
And to make sure I'm not confusing myself, which parts are for front/back;
- GT3 Cup Control Arm Ends.. (Front?)
- Shims (for GT3 Cup Control Arm Ends?)
- Cup Tie Rods (GT4 Cup? Rear?)
- RS Thrust Arms (GT3 RS? Front?)
- Brake Ducts to fit the new thrust arms
- New stretch bolts.
- And some little body kit extenders
I am asking because I am considoring my options, and price is one factor..
I have the RSS stage 1 kit (bought used, not mounted yet), but there are some advantages going only Porsche parts (PAW and alignement at a former Manthey racing employee)...
(I could also consider more RSS parts).

I believe a new approach for camber on GT4 is to get 991.2 RS camber plates and flip them to allow greater camber. You don’t necessarily need additional front arm parts then apart from shims, but significantly fees as the camber plates get you an additional degree anyway.
Then you just need toe links for the rear to keep it balanced with the front. Can get motorsport ones if you like, but they are awkward to adjust due to design.
Seems odd that you want part numbers when the Manthey kit is all Porsche (apart from little plastics parts are from VW Golf R)
If warranty is a concern of course if you fit any non- OEM part your warranty is at risk.
Of course if you have Manthey actual fit the kit, they will warranty their parts and work with their Porsche centre next door to offer continued support, but that’s Germany only.
As for the rest of the kit, no tech who is not looking for anything will immediately see that you have it on unless you tell them, apart from the rear toe links, which are obvious, or they put it on their geo rig as take the setup numbers, so may give the game away.

That is interesting and more cost-effective and simpler way to get to -3 on the front. I suppose this can also be done on the 718 GT4?Then you just need toe links for the rear to keep it balanced with the front. Can get motorsport ones if you like, but they are awkward to adjust due to design.

Other full kits are also available.... Manthey have something, E-motion Engineering.
The key thing is that to get beyond -2° safely you need to have longer or adjustable/extendable steering rods, which come in the MR kit but sure they can be sourced separately, as you’ll run out of thread on the stock ones...which is UNSAFE.
It’s very funny that this topic has popped back up again today.... literally have been on the phone today getting quote for 3-way adjustable dampers. It must be a sign!!

Add cup monoballs LCA's and increase front track on the 718 imo, not top mounts.
the 718 wheels seem way too inward on the car and the CUP parts are longer for a reason.
I have these all round on my GT3. RSS also do a CUP rep part.
Porsche go wider track every model since 1999 and the 992 GT3 will be wider front track again, just copy what Porsche do.
Every tuning shop in the UK will do top mounts, it's the wrong route and reduces track !!! but more but £££ for the tuners.
so where people max out camber at the top, do the reverse an minimise camber at the top mount pushing the top of the wheel out and push the bottom of the wheel out more to get the camber. You will need the "extendable steering rods" of course.

Overall yes - increasing camber via Cup/XL LCA inners & shims is best as you get the benefit of increase track width. the 718 wheels seem way too inward on the car and the CUP parts are longer for a reason.

And to get to -3º you will need shims and the steering rods anyway.

Good tip makes a lot of sense. Will I manage to get to -3 front / -2,5 rear with just the Cup monoball LCA's + steering rods or will I need something else to get there? Does anyone sell this as a kit? Waiting to hear back from Manthey Racing to see what's included in their "extended kit". The 3-way KW-stuff is just too expensive. the 718 wheels seem way too inward on the car and the CUP parts are longer for a reason.
