Because there is a significant difference in power when my gauge is below 100 and when its level at 100. Also it seems my cars runs a little warmer than my fellow 55'ers according to a thread in this forum.
I also have experience with lower tstats and it working. I had a 2006 300C srt8 and its stock tstat opened at 203. I put a 180 tstat in and change the fans to 188 low 194 high and it was a completely different car. Chrysler intended for the car to run between 212-223.

Well I would try to figure out why your car is running hotter than normal first, rather than just installing a lowering Tstat. Things to consider :
(1) You may be knocking, causing excessive heat spikes...
(2) You may have a radiator that is not functioning properly.
(3) Your Tstat may be sticking and not opening fully.
(4) You may have a head gasket leak.

I would first determine that none of the forementioned are applicable and then and only then add the lower Tstat....but that is just me...

I agree 100%. I think she's due for a coolant flush and radiator inspection. On a road trip she runs between the 80-100*. Everyday around town driving she's at 100* on the gauge but never seen it go higher.
