Trust JFP, he knows what he's talking about here.
I live in Florida too and installing a 160 thermo made a noticeable difference in my running temp with a negligible increase in warmup time. I also have a 3rd front radiator installed. This past weekend I did a PCA autocross and was running the car for well over an hour and pushing it hard on the track. Granted it was only in the low 70's outside but it was sunny too. My oil temp peaked no higher than 210-215 and kept dropping to just a hair under 200 between runs, which is where it typically runs now whenever I drive it. Previously it was typical to see temps in the 225-250 range. This is on an 05 C2S btw.
