Has anyone used these with any success? Would it be useful or is it pretty much a gimmick? I've got the 6 pots with the yellow zircon piston inserts but anything that would help shield the caliper from heat would be good at the track....

I haven't used them, but I don't think its a gimmick. I believe StopTech used to either sell or recommend these for high heat applications. Not sure if our cars generate enough heat to make them worthwhile/effective.

Are you boiling your fluid? If so, I'd look at your set up and fix the issue. Out-braking your tires, not enough cooling, wrong pad, wrong fluid, etc. JMHO

I run six pot calipers with the zircon piston inserts in conjunction with Cup car brake cooling ducts front and rear, PFC 08/06 pads, and Endless RF 650 fluid and NTO1 tires. I am not boiling fluid but on a 550+hp car which is about 150 lbs heavier than a GT3 and running on a high altitude (5000'+) track that is brake intensive I think any additional help would be good.

I have them just for fun. Did not have issues before them but i figured they could not hurt especially since I like to run my PFC pads thin. Inexpensive for Porsche world parts cost.

How does elevation factor in?

If you've got the funds burning a hole in your pocket, go for it , but your set up doesn't sound out of whack to me, unless your NT01s are beyond cycled out.....I think it would be difficult to quantify how these shims would help you much.

They work - I know a few guys that run them on 930s.

Elevation very much so factors in because as you go up in altitude the air gets thinner and as a result there are less air molecules available to cool you brakes (airmolecules are further apart)......
