We recently had a Subaru (Forester, not BRZ) that had a malfunctioning gauge.. it was supposed to remain mostly in the middle of the gauge until temps went beyond 220deg then it would climb. At 250deg it should have been at the top of the range, but this gauge was hitting the overheat mark at around 210-215. We changed sending units, and drove it, changed the gauge and drove it, still had the same symptom...point of all this is while I was driving the car in the California summer heat with the a/c on the temps on the scanner would swing wildly...anywhere from 190 to 225+...all of which was perfectly normal. After we added a resistor to the wire feeding the gauge, it remained constant in the middle through a more or less 40deg temp swing.
