I don't do crazy track sessions but just little stints causes the temperature to exceed the JB4 operating temp.
The OEM thermostat opens at 230F, and is fully opened at 260F. A good way for you to have lower oil temps is to simply run a 30/70 coolant to water mixture. Then add in 2 full bottles of any watter wetter product you can find. You can keep your coolant at 30%, because you live in AZ, so no danger of freezing temps.
