206F is not high at all, it is normal. Before an aftermarket radiator I would see nearly 110C before I would turn the heater on.

I have a Koyo radiator with 180 degree thermostat, I see 90-95C every day and have no concerns with the system handling that pressure. 105+ is where concerns begin.

What model year? They switched to a cooler thermostat in '16, if you're concerned you can try swapping it out

Slightly [offtopic], but did the Koyorad drop right in like the factory unit, with NO bumper cover gaps/problems, or AC condenser fitment troubles?
