I forgot to get back to you on those shields for the PBR twin piston Mustang/Corvette calipers.They definately work as I haven't boiled my fluid...

Ti heat shields eliminated brake fade for my CTS-V

I wanted to say again that I'm very happy with the shims so far. At Pueblo the ambient temps were near ninety. Many cars in my run group were...

"Very high [brake] temperatures can also cause the brake fluid to boil with a resultant increase in pedal travel. This should be detected immediately by the driver, as a very small quantity of boiling fluid is enough for the pedal to go right to the floor without any effect; in contrast to the liquid brake fluid, the boiling part is compressible. It is particularly important that when the car has been stopped for a short time -- up to 15 or 20 minutes after a drive in which the brakes have become very hot -- the pedal is depressed for a check. When the car is at rest, brakes act as a heat sink from which heat spreads to the fluid contained in the calipers; brakes which were fully operative when the car was driven may have become totally inefficient after it has stood awhile."

-- Paul Frere, Sports Car and Competition Driving

Brake heat shields vs brake cooling ducts: which is better?

Cooling ducts will help when the car is in motion, however at slower speeds and when stopped in pits/paddock your caliper/seals/boots/fluid can soak up a lot of heat. Our heat shields will help you there, in addition to when hammering the brakes at speed. We are not just making this stuff up, your brake system can suffer significant heat damage long after you have stopped racing.

Consider this quote from "Sports Car and Competition Driving", by Paul Frere:

It is particularly important that when the car has been stopped for a short time -- up to 15 or 20 minutes after a drive in which the brakes have become very hot -- the pedal is depressed for a check. When the car is at rest, brakes act as a heat sink from which heat spreads to the fluid contained in the calipers; brakes which were fully operative when the car was driven may have become totally inefficient after it has stood awhile.

The heat shields are much easier to install than routing ductwork through your car, and may provide all of the protection you need. If you are suffering from serious bad-ass brake heat issues there is a good chance that you will want to use both heat shields and cooling ducts.
