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....

Honestly using any metal as an insulator is not the best idea, especially when in physical contact.
I can imagine this product could help short-term, but over a short period of time the titanium would become "heat soaked" and no longer offer a reduction in conduction into the fluid. At that point it would also have some thermal momentum if you will, and pass heat along after the heat source was reduced/expired.
Not sure it's money well spent.
An actual insulating material would be best, and almost all of them can be cut with a waterjet. Seems like a gimmick.

 

Yeah, that's sort of what I suspected but was curious if someone (other than a vendor selling these things) had any real world data or experience with these. I guess when they start using these on Cup cars then we'll know its for real...

 

Titanium backing plates with a ceramic insulator is a great set up. Just the titanium plates alone helps but is not superb.

Titanium has a low thermal conductivity so it does limit heat transfer to the calipers and fluid. But if you are going to use them without a thermo ceramic backer in my opinion you have sold yourself short. I have not seen any of the porsche titanium backing plates that come with a thermo insulator so is the cost really worth the extra cost????

Many of the good cup car brakes calipers come with very expensive calipers that have titanium pistons.

 

My car already has the Zircon ceramic insulator inserts in the caliper pistons which probably do a much better job that a thin piece of titanium metal would ever do.

 

A titanium sheet with the ceramic insulator between the pad and the titanium is brilliant. The titanium sheet helps more with the convective heat transfer. But really do you actually need more then you already have.

 

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.
