Thermostats and engine coolants

[Barrel]

Can I ask if any one running the coyote engine in their FFR car has switched to a colder thermostat, eg. the Reische 170 degree Ford -50 or equivalent. And what engine coolant is being used. I'm not sure that the Motocraft Specialty Orange Engine Coolant (recommended) is readily available in Australia.
Thank you,
Neil.

We like running with a 180 degree, bringing the engine up to temp.
170 will work. - Chris Engine Factory

Looks like Australia is getting the 2015 Mustang. I'm going to assume it will be sold with the 5.0L worldwide. If so, you might want to see if Ford will carry the Orange coolant.
