Only car i ever drove with a yaw controller was a Vette and I don't believe it ever kicked in since I was in traffic etc. etc. But rest assured I've not new to the Yaw concept and I would strip it just like a pro rally driver would.

No other road car in the world has an AYC system like the Evo. The Skyline has some systems when used in combination do a similar thing. Your experience in the Vette does not apply. You can drift a car with AYC.
I does not come into effect only when yaw is detected at the rear wheels. AYC actually promotes some oversteer when first turning into a corner. On the exit it increases understeer just to balance the car on power out. It also improves traction when the rear wheels have differing grip levels.
All the top WRC cars have active diffs. Pro rally drivers spend a lot of time tuning their active diffs. That is the key I believe development time.
If you have not driven and Evo IV or later, a Skyline or a Porsche 959 then yes you are new to Evo-style AYC.

Erick. I really am struggling to grasp the differences on an active yaw controller between two cars. Thanks for the suggestion to re read your post. I'm not talking about traction control. Yaw being detected at the sideslip angles of the car, I get it. To me the benefits are not great and the weight added is a hinderence along with the intrusive action of the AYC. K. Anywayz the VIII does look proper without fog lights, but it looks less like a rally car and more like a power sedan.

By fixing this you also get more stability of the car, but not because it has more traction on the wheels that have grip. Sometimes, it might be even completely opposite. If you as a driver request from the car to turn, most often doing so with only the front wheels is not good enough. Especially if the front wheels are driven as well (typical FWD that requires higher slip angle to do the same thing as the RWD car). So, you have an AYC to help here. After you start turning your steering wheel, AYC starts to send more power to the outside wheel and makes it to spin more than the inside one (opposite from what would standard slip limiting device do). That creates rotation of the rear end of the car together with the front end too that front wheels are doing.
Since the whole car is now turned where it needs to go fairly quickly, turn angle on the front stays rather low, so tires have even more grip overall. The second part of the work requirement for the AYC is that ones you turned your car enough, you start to correct your steering angle and that makes your AYC to send more power to the inside wheel instead (reliving the outside wheel just for the cornering) and also to the front wheels (which is done by the ACD). That overall stops the rotation of the car and starts to move it more straight and allows earlier throttle application than any other car around.
The best example of this is in that video that is running around (EVOs, M3s and Maranellos) around 4:03 time stamp. In the right hand turn GT-A is rotating in the rear before it even gets to rotate in the front. M3 looses it right after that, but if you look at the GT-A, you would see what this is all about.
Hope this helps...

There is more of a concern about reliabilty and warranty issues with the ayc/acd than about cost. I think the 6-speed falls along those reasons also. They will see how it holds up in the j-spec Evo and further testing and maybe then we'll get it.

"The EVO VIII has been confirmed for production and the first cars are likely to be delivered in February 2003. For the first time ever Mitsubishi's flagship model is going to be sold officially in the American Market and there are rumours that the car will make its debut at the Detroit Motor Show (Jan 5th) and not in Japan.
Mitsubishi Japan is working on some fairly major mechanical changes. Chief amongst these is a new six-speed gearbox mated to a revised four-wheel-drive system that retains the fantastic ACD and AYC chassis systems. There will also be improvements to the already impressive Brembo brakes.
There were early reports that the car might feature Mitsubishi's advanced GDI technology for the engine but it would seem they will stick with the superb 4G63 engine. The engine output will still be limited to the 280ps Japanese "agreement" but it is likely to be revised with more torque and flexibility."
Official info recieved from Litchfeild Imports, who had one of the first Evo VII's in the country, and tested for eight months. So, they are a pretty reliable source when it comes to EVO info.

I'll sum it up: 265+hp(likely 265-270), Brembo brakes, Recaro seats (of some sort), No ayc/acd, no 6-speed. Same 5-speed as Evo VII. It'll have an lsd setup. No Ralliart in the US. No Ralliart dealer affiliation. The front bumper will give better aerodynamics and improved flow to intercooler, improved carbon fiber rear wing....etc...etc..that kind of sums it up..
