There likely would he no benefit for you for a lower temp tstat. IMHO there is no benefit to any situation for a lower temp tstat. Once you are above the 185F rating of the OEM tstat it is fully open anyways. All a lower rated tstat is going to do it make it harder to get up to operating temp when you are doing anything other tuen driving spirited on a hot day.

What is your concern with temps around 200F? Trying to bring them down will drop efficiency of the engine.

I've tried to wrap my head around why low temp tstat are even in the market and I've failed to find a reason why. I get the full removal of a tstat in a race car (to maximize coolant flow) but not for a lower rated temp tstat.
