Thankfully, I rarely ever use the freeway lol...

I need to load test the car and see how much load it takes to hold 55mph with these new tires and other mods...
I like the look of the car lot and congratulations on the air dam

I think those coolant temperatures might be considerably too high. I used to have an alarm set on mine to trigger any time the temperature went over 206 degrees. Now I have it set to go off whenever the coolant temperature goes over 200 degrees. I think the kinds of temperatures you're seeing could lead to premature head gasket failure.

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
