For those of you who have gotten rid of your 370Z

Same with the 335i. If it didn't have limp mode, no one would complain about oil overheating, even before BMW retrofitted oil coolers.

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.

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.

What I'm talking about is if you're going hard through a corner, let's say on entry to apex, the Z is most likely to lose front grip first. On throttle you can kick the back end out, but that's a different type of oversteer (and the type of oversteer you don't want too much of, I might add.)

Regarding track times, it depends on the track. The 5.0 and Z are about equal through the corners. Take a look at the most recent C&D "best handlers under $40k" as they have pretty good data that separates time through corners and time on the straights.

What I've been saying all along is that the two are "about the same" in the handling department, with the edge going to the 5.0 (TO ME) because of a more neutral balance (TO ME). It could be entirely different to someone else. Either way BOTH cars are excellent corner carvers.

After all it does have a square set up. You get 255 mm tires all over, which are quite large for front tires, but on the skinny side for rear tires. I actually think 245 mm are too skinny for front tires on the z, especially given the forward weight bias. That may be responsible for much of the understeer. 255 or even 265 mm fronts may be better.

I still don't think the mustang can carry as much momentum through corners as the z. If it laps a track on average at the same time as the z, give or take a second or so, then it has to be losing time somewhere given that it gains a lot of time over the z on the straights. I don't remember the C&D article. I'll check it when I go home. I do remember that in the recent DSport RWD car of the year, the mustang was a bit slower than the z, and actually was even slower than the camaro ss. Can't remember which track they did the testing though.

The C&D article is much more objective and the testing data is interesting. For instance, the Mustang actually had the lowest body roll angle of all of the cars tested. The Miata had the highest.

Also, regarding losing time in the corners, the Mustang and 370Z had the exact same lap time with the straightaways removed at 63.3 seconds each.

For all intents and purposes, the cars are dead even stock-vs-stock in the corners, which supports everything I can tell after having spent quite a bit of time with both cars.

That said, the Stang is dead even with the Z in handling in practically every objective measure and real world application. It wasn't faster through any corner, but it wasn't like it was even a half second behind in any of them either. It will outhandle most cars available for purchase, and that's in stock form.
