High temp due to it's proximity to the rotor which gets nice and toasty.
The car is a dedicated track car so as long as it works, is not a safety issue and can last a dozen track day events per year then I'm good with that. I'll check out your link. Thanks.
The design will probably have the main hose feed the center of the rotor thru a mounted backing plate. We are also looking at adding a second hose to feed air right onto just the caliper to keep fluid temps down. Overkil? Probably, but the last thing I want on track is faded brakes.
