Only time you need it is if you take your car around the road course race track often. Or if you do back to back hot laps at the drag strip, it is recommended as well. The whole purpose of the low temp thermostat is to give the cooling system an extra margin on heat capacity. Say you have a 170F thermo(that's what I have in my car, the TRD one). After one pass down the drag strip, you will probably be at around 190F. If you go back and hot lap a second time without waiting for cool down, the next lap will put you at around 210F or so. The lap after that you will be at 230F, and then you need to cool down at that point. You get 3 runs before needing a cool down. Now if you're on a standard 190F thermo, you would need a cool down after one or two passes. It's recommended to fully cool down between every pass to get the maximum power but in some race events, long cool downs are not allowed. On a road course track, you can push the car harder between cool downs and not risk overheating as much.
The cooling system in my car is pretty robust(heavily upgraded) so I've never overheated at the track. One time I did 6 back to back hot laps at the drag strip and my temp kept steady at around 210F. On the road course my temps usually hover around 200-210F average.
So in short...you don't need a low temp thermo unless you are tracking your car or taking it to the drag strip often
