so, i see it as z4m vs. 370z with oil cooler and diff cooler. i'd guess that the two cars would be a pretty close match on the track.
A common misconception or a poorly designed oil cooling system. If you are concerned about warm up times a thermal switch/valve much like the one in your cooling system keeps oil out of the cooler until it comes up to temp. Oil coolers are a good idea on any modern engine as much of the cooling is done with the oil now. The 370Z will hardly break half way on the temp gauge for engine coolant yet you'll be in limp mode with the oil overheating with track use and no cooler. An oil cooling system should be thought of as an anti-oil-overheating system rather than one that keeps the oil temperature low. Its important for your oil to be running at temperature for flow/lubrication and a proper oil cooling system will do just that.


For track use a diff cooler isn't really needed.
