There is really no fairness in trying to contest a RWD Z to an AWD turbocharged car. Yes, you can get 30 whp JUST from a tune on a Subaru.. I don't know on a stock 370 what you would get, but it aint that.

Anyway, there are benefits to each car... IMO the wider tires and them being Advans is equal to the WRX being a computer controlled AWD car. That's my opinion at least.

And a V6 Mustang? Come on man.
I said that. Summit point is an example of a track better for the subie. But doing something like Laguna Seca would be great-- it's an epic track, and I care about LS lap times.

Again, they are different cars, but they do "compete" in that people cross shop them. People that plan on tracking their cars almost universally pick something else.

The V6 beats the Z on most US tracks, just so you know. It's actually faster than the GT on tight tracks, and is usually just a few seconds behind on other tracks. With the limiter removed (top speed is 117 for insurance reasons), it puts .5-1.5 seconds on the Z around VIR.

Where are you getting all this infor?? The V6 Stang is faster on most US tracks then the Z?? I'm just curious? How do you know the V6 Stang puts .5-1.5 seconds on the Z at VIR?? CarAndDriver never tested one that was modded with a tune.

curiously, car and driver isn't actually the only source for number. In fact, they are one of the worst.

ok, let's say that with the courses you have driven, other cars you've owned.. someone from Nissan says "hey, what would you like to see added to the car?" You say __________________? Let's say power is limited only to the current NA mods, so you can get maybe 330 whp at best when it comes to power.

Meh I don't like that question. Power is what I would want more of. Then weight reduction + balance. Also an actual DCT. Basically I want a lighter GT-R

I think I said this earlier, but the things I would want changed are these.

Slight tweaking of engine/different engine. I want something with better top end behavior (the NVH up high is pretty bad). I could live without this if the other items were changed.

Oil cooler and diff cooler available from the factory. Both of these are much needed items. Most people don't know about the diff, but it tends to overheat something terrible with any hard driving.

Real LSD available from factory--preferably a Torsen. The VLSD doesn't cut it for real driving.

The biggest thing though, would be the weight distro/inherent understeer. I think if they could drop a few pounds from the engine, or move it an inch or two back, the car would be brilliant. I could forgive the other shortcomings if they did that.



The Z really has a brilliant chassis-- it's very stiff, and inspires confidence. A few small changes and it really could have been a home run IMO. I think that with the same setup, but the engine back an inch or so, we'd see the Z tearing some stuff up.

So you don't think the 53/47 current weight distribution is good enough?

If it were me, I would lose about 200 lbs from the car, max out the NA mods, maybe beef up the sway bars, and of course the oil cooler is going to be needed... though I did 3 VERY hard runs tonight after the car was already warmed up and it just hit 220... but it's pretty cool tonight and it's not lap after lap either. Pads would be needed. I wouldn't spend some 800.00 for Nismo pads however I can tell you that much. I think that would be quite a nice handling machine.

Coming from an s2000, I will tell you the Z probably leaves a second or so on the table with the current weight distribution. 53/47 is actually pretty shitty for a RWD 'sports car'

I think factory sways aren't that bad tbh. It'd be nice if the rear was stiffer though.

Pads are something you always change for the track. Nobody runs track pads on the street. I don't really care what pads a car comes with, I'm gonna take 10 minutes and switch them at the track.

Weight is reasonable for what the car is. Dropping 200 lbs and you lose stiffness or comfort--neither is really an option. Of course, in an ideal world, it would be great.
