Spook's GT3 arrives!

Well if we are continuing on brakes, why do Porsche steel rotors rust seemingly more than other marques?

Great looking car though Spook!
 

Car brake discs are generally made from grey cast iron which, among other things, has high thermal conductivity but low resistance to rusting.

Maybe other manufacturers include elements such as chromium to reduce rusting - possibly at the expense of thermal conductivity..??

Oddly enough, motorcycle discs are usually stainless steel.

My Fireblade disks are stainless steel and frankly the braking force is phenomenal and enough to throw you off if you are not careful but I hardly ever use the rear brake as the moment really hard braking occurs the weight transference to the front takes the weight off the rear tyre.

Hi Guys

I don't know about loosing the thread but I have lost the plot! (Sorry Captain I must have dropped off again at the back!)

I was originally worried about reduced mileage on the hubs/bearings due to centre lock wheels on track use and then got tied up about PCCB, which also will be on my S as standard although I would not
have specked either if they cost more.

Can anyone either redirect me to the centre lock wheels debate or show me where I can get the necessary information?

Thanks to Clive for allaying my fears about Rotor life, when I get my car on the track I will be able to comment on their effectiveness.

Cheers

Have to say I think it looks great, it's a pity Porsche limit production for reasons best known to themselves.

I've been to Zuffenhausen many times and the last time I went in September, there were turbo S's and GT3s on the line one after the other and Porsche could make as many as they wanted but choose instead to limit production so making way for, dare I say it, rather dreary lesser models. It is simply not the case that GT3 production is limited for technical/supply reasons. It's a purely business decision.

I've told my salesman that since he can't supply me with a GT3 (in spite of him pushing a turbo S for all it/he was worth, especially the two "frustrated" sale examples sitting in the showroom), I'm going to stay where I am. It's a lost sale, not that Porsche will care one iota about losing business from some oik like me.

His theory was that GT3 production is limited because they lose money on every sale and only want to make as many as are needed for racing homologation purposes. True or not, I do not know, but the demand for the car suggests the other incarnations are tilted too far in the direction of GT/Autobahn stormers.

Popped into Dick Lovett Swindon yesterday and they have a GT3 with 85 miles on the clock on the forecourt. Very nice too. Why the sale? Well, the owner decided he really needed a TurboS. Go figure.

As far as the thread staying on topic, who cares... really interesting debate and fascinating thoughts on unsprung mass. I was changing over wheels on the Cayenne and they are really heavy, as Nick says, that is the place to save some weight and I can see why the idea of carbon rims takes hold for exotica. For road use there's not much that can be done about the construct (and weight) of tyres themselves, I guess.

Priced at an eye-watering £132K, [:(] will anyone really buy that instead of a Turbo S, I wonder ? [8|]

Carbon ceramic rotors are approx. ½ the weight of grey cast iron and provide a most valuable total saving of around 20 kilos of unsprung weight.

Carbon fibre wheels on the Cayenne would be a sensation, Peter! [:D]

Clive,
 
And an Exeter December (per the ad) supplied GT3 at JZM for £123,900:

There's lots of myths going around about the 991 GT3, but that one takes the biscuit.

In fairness it was the same with the 997 GT3 and 996 GT3 Mk1 and RS. The production nos will probably reflect the true underlying demand for the first series. If Turbo production was similarly limited then we would probably be seeing the same hype.

£154,521.00 - interesting price! [:eek:]

Maybe they'd knock off the £21 for a cash sale. [:D]

Clive.

If it was possible to order one new from the factory that specification would be about £115K unless I have missed something off the configurator that's quite a premium, the Black Turbo S (may have sold by now) was a cancelled order but wasn't registered, asking price £149K which is list for the specification.
 
What is this car? Says 2013 GT3 RS (!), photos of 991 GT3, as far as I can tell but not the actual car, and the spec says it has a 3996 cc engine/500 bhp, reg Sept 13 and only done 50 miles Sounds a bit fishy to me![;)]

Fom his eBay "showroom" the address is given as W1H 1DP. Look it up on Google - I wonder where they keep all the exotic cars?[8|][:)]

Story on the Exeter one at for sale at JZM..

So a genuine reason for sale then, not really profiteering - just a £14K premium! [:eek:][;)]
