55deg Motorsport thermostat

A few have said they improve temps but I'm at a loss to understand how they work when engine is at full bore.

Surely when car is hot and running in race conditions the oil is hot and oem water stat is open normally anyway, so why would it opening earlier help cool the engine and eventually help reduce oil etc?

Here is what Turner say

E46M3 Motorsport Thermostat 55C (Also fits Euro E36 M3 engine) A Genuine BMW part this thermostat opens at a much lower temperature than stock to keep your S54 engine (or Euro S50/S52 engine) running cooler in race applications.
