I fortunately had a set of "just in case" Pagid Yellow with me and the other 3 sessions went great.
What a piece of garbage these pads are: squeal like hell on the street and dangerous on the track.
If any of the posters who like them wants a whole set (f/r) of this junk you can have them for free, you just have to pay the shipping.

I dunno', I have no experience with gas stations and air tanks - it may be crap but your example is not a very good one based on Physics and the ideal gas law. When you put air in a confined space and compress it the air will get warmer. When you expand that volume of air (like spraying it against your hand) it will cool. Now, the warm air that had previously been under pressure carries moisture (the concept of humidity; the warmer the air, the more moisture is can hold) but rapid cooling, like being released from pressure, will result in the air no longer able to hold the same amount of moisture - hence condensation and water on your hand. Additionally, and perhaps more specifically, the sprayed gas station air, as it is cool, will cool things that it comes in contact with. The micro-layer of air around these objects cools and more water condenses - the obvious example is condensation on a can of cold soda.

So, all things being equal, compressed air in a tank going into a compressed environment, like a tire, should be a direct transfer. Any impurities the air may have picked up in the tank will remain (but I don't see what that has to do with the functional quality of the air or how it may degrade your car's performance.

I'm looking to upgrade my pads from stock and this thread looks like it has some valid info. I could go with Pagid and just keep them as dedicated DE pads but it sounds like the endless pads may be a decent compromise and suitable for my DE level.

I used to always caution younger drivers away from upgraded pads designed for some or full track use because they would not work as well when they were cold (which also held true to highway driving). The last thing you want to have happen is someone have to hit the breaks in an emergency after a long time coasting on the highway and have them not respond adequately.

How well do stock 997 (standard brakes) rotors hold up to upgraded pads? Is there a limit where you need to look at upgrading them to avoid warping?

Stock pads i do not use, for street pads with least dust i think are ebc red stuff, now i use stop tech street pads. For track you cannot use either. Lower run groups folks, green/yellow can probably use ebc yellow stuff but they can fade if pushed far and require good cooling. Any track setup requires air ducts, gt2 or at least smaller gt3 ducts in front and ducts in rear, upper and lower. With proper air flow your rotors will crack less. Also, what is good about dba rotors - they have color marks do you can see level of overheat somewhat. I have in a box both rs29 pagids and pfc08 pads, pfc has obviously better bite but makes rotors very hot. It is probably not smart to run them without ducts in place.
