Nope. But again, most cars do not have an oil temp gauge. The oil could be cooking and the driver would be none the wiser. The thing is, if the Z did not have limp mode or an oil temp gauge, no one would be whining about an oil temp problem, while they lap the car all day long, melting their bearings in the process. Same with the 335i. If it didn't have limp mode, no one would complain about oil overheating, even before BMW retrofitted oil coolers.

When it comes to balance stock-for-stock, the Z has a lot of understeer and the 5.0 is very neutral.

Define " a lot". I have no problem getting the back end around with a bit of throttle. At least on the stock tires. With my AD08, understeer is a bit more prominent, but if i take out 3-4 psi of air from the front tires that deals with most of the problem. There's still a hint of understeer, but throttle application can get rid of that and even induce a spin out.
Also, if the mustang has the same handling as the z, why is it that the v6 mustang, which has the same straightline performance as the z lose out on laptimes? And why is it that the 5.0 GT that blows the z away on a straight line post laptimes about the same or marginally faster than the z? If a mustang is gaining so much time on the straights, it must be losing some time to the z on the corners. Otherwise, the discrepancy in laptimes should be much bigger.

Besides that, pretty much every car comes with an air-to-water cooler at the least.

Do base corvettes have an oil cooler? I recall reading somewhere that one of the upgrades that come with the z06 and zr1 over the base vettes are oil coolers.
