I guess with no need for leg room in the back they can shorten the wheelbase to make it more agile and no need to RWS.
Clever people those engineers.

I’d imagine they charge for it...and I am fairly sure the answer would be something along the lines of “each set up is bespoke”. I actually have my first visit to them in a couple of weeks, really interested to see what it’s all about. In normal times you can stay and watch, not sure if that’s possible at the moment.
Haven't used Centre Gravity but evidently they have a good reputation.Like all setups and irrespective of the quality and age of the equipment it will only be as good as the person undertaking the work at the time.

Not sure how many miles you have on your GT3RS, but at around 1500 ( Inc about 1k on track) the blue engine run in light goes out. Then the engine drives like its on another Map, it really comes alive in sounds also. I am really looking forward to get this new GT3 on track have some Cup 2 R ready to go on, based on just how good my 991.2GT3 was with just a few GEO and ride height settings, have high expectations for this new car..
Anybody know ... what would be a good geo set-up on a 991.2 GT3 ?For mainly road but some track work ?
Amazing family business, who really know their craft from AC to modern GT cars. They have time for their customers and really want to do a great job for them - charming people and great value IMHO - very rare in this day & age

To be fair, I was not after a road set up. Reason being Imv you cannot get close to use the performance of what these cars can do on public raods, last thing they need is more camber etc for road use. For mainly road but some track work ?
It was track use that I was after. Camber, toe, right height, Wing adjust, etc. I gave the settings to my Local OPCs, they did all the work. It completely transform the car on track. On roads it was Ok, but care needed to be taken with right height. On these cars with RWS its important that who ever does the set up has the right service tool to re calibrate the RWS sensor on the steering. Other wise it will feel very odd on the back end.
Maybe it's been mentioned before, I didn't look back through the previous posts, but String Theory garage have developed various set ups for road and / or track in conjunction with JCR. Ben spends a long time getting everything spot on including ride heights and corner weights, it made my 991.2 much more fun to drive. He's not expensive either.

Was just about to mention these. If I was after a setup this is were I would go. JCR knows his way round these like no other. This is were my 992 Gt3 will be going.APOLO1 said:

ApoloI thanks for the comment on JCR but can you let me know where they are based & a tel No if you have one Thanks.
I see that the other chap has very kindly provided this info above. But would add to what Yellow and others have said for road use I would not bother with a set up, stock settings when set up right are brilliant for road use, just make sure the tyres are set to 31/33 and away you go. Aside to my own cars, I have driven lots of these 991 cars with RWS they are very sensitive to set up, they only need to be out a little and it will make a big difference to the way they feel and handle. If you are intending to track the car then I would get used to the stock settings first then when you feel more comfortable take the car to String Theory as mentioned above.Edited by APOLO1 on Sunday 7th March 18:37
TBF if we look at what Chris asked for it make sure to was set nicely for road.
That could well mean OEM settings, but who knows what state the car is in as it is a used purchase, and even in the case of new from OPC, settings can be within OEM tolerances but the car still a mess.
So he want to get it checked... standard fare for when you pick up a new to you car.

Standard factory settings on both 991.2GT3 and RS are pretty spot on for road use as it simply flows over rough or cambered surfaces. OTOH on track the standard settings are not ideal as the front tends to understeer on the limit. Adding camber to the front will need too much steering correction when driving on rough roads imo.Edited by APOLO1 on Sunday 7th March 18:37
All 911s are set up by factory to be safe and manageable for road use which makes perfect sense.
Thanks all and to be fair ... I did change the subject, sorry.
Some very useful information and I'll get it checked ... but left as standard.
The car is still on it's original tyres after 5500 miles and there's 4mm on the rear and 3mm on the front ... suggesting that understeer is more of an issue ... but not driven hard ! Wear is a tad more on the inner shoulders ... negative camber as standard is -1.5 degrees so this all makes sense.
I have first pic which I'll include ... better ones to come on a separate thread !

Just gone and measured mine which are 4 mill on rears and 5 mill on the fronts, measured every groove and all the same.Ive ran Cups on my last 3 BMs and they start off at 5.7 mill new, I think the Cups on the P car start at 6 mill new.You would always get 2 for 1 on RWD so 2 changes on rear to one set of fronts and my GT3 looks like its going to be the same .
Looks like you have a prob with your fronts out of tracking or something, you shouldn't have any wear on the inside shoulders which suggests that something is not right.
My tyres were brand new and have put 6.5k miles on them so far, I couldn't get 4k miles out of any set of rears on my BMs so it shows you how good the traction is on the GT3, its not a DD and only used when I am off to blow a way the cobwebs and is driven hard .
Have never felt any understeer and think you would have to drive it on the edge to feel any on the road, RWS has killed understeer in these modern GT3 cars.
I would just get a basic tracking done too see if anything is out .
Car looks terrific by the way.
