DaveGordon:bluelines:My GT4 brakes were rather noise until the first track day *squeeeeeeeeeek* Then they went quiet.
+1 mine were embarrassing til I spent a day on the track.. Been ok since
I would also think that one serious day at the track will get rid of the noise .
I have racing pads on my Carrera . They made also lots of squeaks when driving on the road . Once I hit the track , they became silent after that .
You can not compare road braking ( even hard ) with track braking .

vantagesc:Whoopsy:Porker:That's only normal for agressive pads, but I would be surprised the stock pads are that abrasive and track oriented. I think a day of good use should silence them as Bluelines suggests.
I was told by the shop foreman that they are that aggressive. As you have seen from the g-meter reading I posted not long ago, if the noise didn't go away driving like that, it will never quiet down.
The prolonged exposure to heat at the track can allow the pad to lay down a transfer layer or at least better mate with surface. Fact that high negative g was achieved is not enough IMO
I agree. Whoopsy, when is your track ready?

Some time late spring
It started raining last night, took the car out for another drive. 15 degree or so.
The 918 on same sized Cup2s are still king with the superior traction of awd.
The Dunlops on the RS feels better than the Cup2s on my Speciale in the wet. But it's not quite a A-A B-B comparison, different car configuration and different sizing.
Either the Dunlop compound works better at lower temperature, or the extra groves on the shoulder really do a better job at evacuating water, I can't really tell, yet. Will need to wait for a dry but cold day.
But it's really really cool to see water sprays coming out from the fenders vents :)
Oh also, the engine gets up to operating temperature very quickly. From a ambient 26-28 degree, the cold engine lights goes off after a couple minutes at 46-47 degree. Then another 5 minutes or so it will be at 88-90 degree operating temperature. 918 was the same thing, the temperature climbs really quickly from cold starts. My Ferrari climbs bit slower though.
Makes you appreciate how hot those engines are, to be able to heat up so many litres of water so quickly. Boiling a pot of water at home on the stove takes longer.

The new DFI motors are designed to run at a higher temp for more complete combustion (better emissions). They close part of the water circuit on the warm-up cycle, so it has to boil a smaller pot of water
On the GT4, the water temp goes down (after reaching operating temp) when you press "Sport" button for the transmission. Probably does the same on RS (might try it for fun).

The K-spec Cup 2s on the Ferrari are also apparently harder/less grippy than the N-spec ones on the 911, too. Someone on Rennlist put some K-spec ones on the back of a GT3 for an experiment and it turned into a drift machine..

Whoopsy, Thanks for all the feedback you have provided for the RS! My car is supposed to be here next week. Couple of questions:
1) Do the red calipers match the lava orange well? My car has the same color combo and that's one of my concerns of not going with PCCB.
2) Is the stock exhaust adequate? How aggressive does it sound your Speciale or 918? I am looking into the side muffler bypass.

DaveGordon:The Dunlops worked surprisingly well in the cold for me... It was -6C when I picked up the GT3 and driving it in those cold but dry conditions wasn't the sketchy experience I was expecting...
There will always be trade offs in tire compounds, I imagine Dunlop trades lap times consistency, durability for the ability to start gripping at a lower temperature and provide a higher ultimate grip.
Cup2s are bad when cold, but lays down consistent grips once at operating temperature, might not have the ultimate peak grip of the Dunlops but will last longer.
The K-spec Cup2s were downright scary when cold on my Speciale. Almost as bad as the Super Sport on my previous F12 at below freezing. N0 spec Cup2s on my 918 were decent enough when cold, but I didn't test my luck below freezing.

Congrats on getting the RS.
1), let's just say my eyes don't really focus on the red calipers, they don't really clash with the orange, personally I think the amber corner lens on my car clashes more badly. Realistically, neither the red nor yellow callipers goes well with the lava orange. I would have preferred black ones.
2) exhaust sound is very personal, my perception of too loud could be your normal. The 918 is definitely the loudest, with the exhaust 2 feet from my ears. The Speciale is loud and noisy, obnoxiously loud, annoyingly noisy. It's just noise most of the time. But at the upper revs it started to sound like music to the ear. The RS sounds nice enough even without pressing the exhaust button, at low revs I can still hear it but I can carry a normal conversation with the passenger. It gets louder with increasing revs, and sounds glorious that's for sure. But still the V12 in my F12 trumps them all.

Moser:Does anyone know if you can get a UK specs RS from your local dealer outside the UK if the car hasn't gone into production? I mean if you found out you were moving and needed a right hand drive car, could your dealer technically order it for you?
I did the opposite for my Boxster - ordered a German-spec car from the UK. That was no problem, although it added quite a lot to the delivery time. I think most large dealers cater for export cars to some degree.. How it might work for an RS could be another question..

Thanks for the reply Dave, I can use this info now if my dealer tries to tell me it's not possible . I'm moving to Cyprus from Beirut this week, and would like to take the car with me there when it arrives, I've got to check the emissions issue as well, as the cars coming to Lebanon are gulf specs.... I hope to get a reply this week....

good luck to you. about two years ago i wanted to buy a gulf spec GT3 in saudi arabia, keep it there for a couple of years (i spend quite a lot of time in saudi) and then import it to austria. neither porsche austria nor porsche germany was able (or willing) to tell me whether this works or not. issues were emssions, the beeping noise at 130km/h characteristic for gulf spec cars and others. in the end porsche austria told me that most likely (!!!!!!) i will be able to register the car in austria but i won't ever be able to sell it - some kind of personal registration not valid upon resale. the austrian registration office told me to bring the car to them, then they will decide. unbelievable. you can probably appreciate that porsche saudi arabia was even less helpful. in the end i decided to stick with taxis when in saudi and buy my cars in europe.
