Tips for brake modifications prior to 'Ring trip?
Discussion
Best trackday mod of them all - park with the handbrake off after the run, whack it in 6th and not on a hill.
Other than that, check out your cross drill holes on all sides - running Pagid blues on 993 gt2 and 996gt3, we often had to use a drill to "clear" the old pad material from the discs. Made a huge difference to the temperature of the brakes (although SRF really is unboilable =) )

well, SRF is about the best fluid you can get, now what about those pads..
Which EBCs were you thinking off?
He just mentioned EBC's. Which are the best ones for track use?Which EBCs were you thinking off?

I'd say just changing the pads should be fine. 4 piston calipers onto huge discs should be sufficient stopping power.
HTH
Thinking more along the lines of boiled brake fluid, over cooked pads, etc. Be it a 911 or not, it's still only a road car!HTH
well, you've got greens, yellows and reds,
greens are for corsas, yellows are a little more track like, reds are getting into decent stuff, but might be a touch slippy when cold.
I doubt they'd be too bad, but i'd look around at other options.
If performance friction cover your car (which i guess they will) their Z rated pads are great value, and then they have race compounds too.

There is only one section of the NS that is even slightly challenging to brakes - from Metzgesfeld "2" down to Breidscheid (circuit low point near village of Adenau).
On this map, it is the sharp left just before km 6 to the sharp left just before km 8:
Because that section is steeply downhill, with a lot of bends, newcomers tend to ride their brakes for long periods. It is that, rather than short, sharp applications, that will overheat brakes and pads and potentially boil fluid.
Keeping the car in a low gear through that section will help, but letting it roll without touching the brakes for parts of it is more important.
At least for brakes, the rest of the circuit is no big deal.

Motul RBF Fluid and Pagid Blues or Yellows would be more than sufficient. No need to upgrade discs.
Then only do one lap at a time and then come in and let everything cool down with the handbrake off before going out again. I generally give it a minimum of half an hour before I go out again.

Hmm, been around track days before - after serious driving do the following things -)
Drive last lap (maybe not in this case) carefully, avoid hard braking
when you come to pits area, let the car idle for few minutes, wait in the car in case ground is not level.
And DO NOT USE HANDBRAKE after the run when you leave the car. Good advice from Atomic Gibbon - but when you park do not use higher gears. Use either first gear or reverse. The reason is obvious - when car is parked in say 5th gear you can still push it or it can slide down hill. Actually reverse is best, its the shortest gear...

Is it worth modifying a car before a trip to the 'Ring? Won't it result in problems you've never suffered before and too far from home to fix?
For the first trip take the car you're familiar with, I'd say. Just make sure it's in good nick.
I don't know what fluid Porsche use as standard, but for the small cost I would definately upgrade it to something like SRF. Can't really see any pitfalls from this and it's certainly better than realising you've boiled the fluid after 4 or 5 corners.For the first trip take the car you're familiar with, I'd say.

What are standard Porsche pads like when hot? I would have expected them to be pretty good. As HeeBee says, some things can be better the devil you know.
For the last fortnight out there they have had something of a heat wave.
You can monitor the forecast on several sites. This one is usually as accurate as any:
http://de.weather.com/weather/local/GMXX0155
They all tend to get the temps right, although rain can be quite unpredictable.
Apart from in exceptional outside temperature, however, I'm telling you, you really do not need to worry about the brakes overheating at that circuit. (I am assuming that your dad does not weigh 23 stone and would not have two obese passengers in the car plus bags of sand in the boot.)
Watch it on the downhill section noted above, and use short, hard braking rather than gradual and continuous. Otherwise it really is not an issue.
