I have an 05 STI. I was driving today and noticed when accelerating pretty aggressively my Rear Diff Oil Temp light came on for about a few seconds. Is this normal?? It is the first time i've seen it. No mods so far... However i do have a ~150lb subwoofer box in the trunk (which makes the car sit pretty low in the rear) that I have been contemplating taking out. Do you think if i continue this way will eventually run into problems? Should i check tire pressure? Or is this common. Any help is appreciated.
