Does the proper set up fairly transform it Colin?
I do find the "Transforms The Car" phrase somewhat overused on here, but the difference is very, very tangible once you are carrying speed. Having the front end pinned down just makes it lovely to drive the back end balanced on the throttle, which is what suits me. It is also fun in day to day driving - even at normal road speeds having that amount of front bite can make even mini-roundabouts somewhat less tiresome ;-)
As Jon pointed out above - the other thing that I have is the 245 front tyre on mine instead of the 235 stock size. This is the standard front tyre from the 997.2RS (so no issue if you are into your N ratings and so on) and I favour it as I find that it slightly better helps the car resist understeer on corner exit under power. I stayed with the normal 305 rear and find the balance is just where I want it so have not tried putting the wider RS rears on too (though they certainly would fit the 12j rim if you were after more traction).
The thing is : the really special thing about the GT3 is that it can basically be set up to drive how you want it to and to get the best from your driving style. There are other ways to go about it as well. Nick W went to 4 degrees on the front of his 3.8RS (with a notch less on the roll bars IIRC) and he can hurl it into tight corners, but especially on the Cup+ it developed a more serious appetite for tyres as a consequence.
My setup is more compromised than most of the track day regulars as I use it as a regular road car too (and always have since I got my first one over a decade ago) rather than a pure track trip toy. At stock ride height for better speed bump friendliness it has been said to appear on stilts parked with Danny, Jon and the 2 Nicks (who favour taking it down to a more track optimised height). If you are trailering it then you can actually get it on a completely track focussed geo which will be massively grippier than stock, but that will make it quite a bit less satisfying as a road car.
With a GT3 you can have your cake and eat it. Extending the metaphor - if you take the ingredients to a baker who really knows their stuff they can make it how you like it, so that is why we all run off to our favourite specialists to set them up. Centre Gravity in the Midlands are my go-too, but there are many others (Fearnsport, Sports and Classic, Parr, JZM and plenty more up and down the country). Nobody that I know would use a main dealer for geo though - I wouldn't even use them to set it to stock (when I acquired mine - from of all places Reading - it was not as it should have been).
