Track day brakes upgrade
Discussion
Did my first track day over the weekend and must say I wasn't overly impressed by the standard brakes' fade resistance.
Braking performance was strong enough, but after 3-4 hot laps they'd become pretty much useless.
What options do I have to improve fade resistance? Any recommended pads, brake fluid, brake hoses, other?

I'm quite happy with the braking power, so I was really after ways of improving heat resistance/sheilding.
Pagid pads sound like a good idea, what about braided hoses (not sure if they come standard)? Any recommended brake fluid upgrades?
Any other ideas on how to improve cold air supply and heat dissipatio?

I tracked my '09 V8V quite a few times. After destroying a set of OEM discs, a set of OEM pads and a set of Carbotech XP10's (while running high-temp. fluid), I replaced the discs with 2 piece floating Brembos (same discs as used on N24 cars), and the pads with Pagid RS19's. I also tried RSC Tuning's brake cooling ducts. With this setup, I could run fairly hard for about 15 minutes at a time, after which overheating again became an issue. With proper cool-down, I have had no further issues with the discs or pads. But they still run way too hot.
The car is heavy and needs better cooling, plain and simple. IMO (but based on my personal experience!) and with respect to Stuart, who sells some great products, the RSC ducts are useless on 4.7L cars and he should not be marketing them as an improvement. They have to be routed differently than on the 4.3L cars, with such a bend in the ducts I doubt they provide much air flow, and besides, they are trying to scoop air from under the car, not in front where they should be. Bottom line: if you want to get serious, start cutting into your bumper, or replace it with the V12V front fascia with integrated cooling. I was at this point before I sold the car.
On a side note, the OEM RE050's are IMO garbage on track. They don't have much mechanical grip to start with and turn to a greasy mess quickly. I found RE11's an outstanding dual-purpose tire, not far removed from an R-compound but cheaper and much better on the street. I actually preferred them to the OEM tires for everyday driving, too. These tires were still going strong every time the brakes overheated!
On another side note, be aware that without better cooling the brakes will run so hot that the calipers will discolour - mine were grey but turned a gold colour - not ideal if you are picky about the looks of the car.
Hope this helps...
Thanks Quench, that's very helpful.The car is heavy and needs better cooling, plain and simple.

How did you find the Pagid pads on the road - is the noise bearable?
Where did you source the 2-piece brembo discs, do you have a part # by any chance?

I'm going to retract this after recieving an email 
I was previously advised by a guy in the US that the S brakes ARE Brembo GT kits
I seems they are far from it and much better than the GT kit
Perhaps they are the new Brembo GT-R(acing) kit? A step up on the GT kit I beleiveI was previously advised by a guy in the US that the S brakes ARE Brembo GT kits
