This is NOT true. You absolutely need to let a car warm up still. Think about it. Oil that is not warm is much thicker....using high revs on a cold engine is definitely bad for it, it stresses all the components far more than once the oil is hot.
I wont rev a car past around 3500 until the engine is warm.

You are absolutely right that you should let an engine warm up before driving aggressively, or at all, but the oil is actually the opposite. The BRZ/FRS asks for a 0w-20 oil, according the owners manual. That means at 40 deg C (100 F), the oil is a SAE 0 weight, while, at operating temperature (100 deg C or 210 F), the oil is a SAE 20 weight. The viscosity improving additives are added for the very reason of making the oil thinner at cold start, and thicker at operating temperature.
