How to make an AWD car rotate
STaSiS engineering has it right...

Notice how the car has ZERO understeer... i've never seen any in car video from an evo that looks like this. I called STaSIS and they said they work with the rear diff and rear valving to help with this. They also said its alot of Chip using left foot braking.

With just a Cusco rear swaybar, an aggressive alignment (including rear toe-out), and lots of trailbraking & left-foot braking, I find even my relatively stock 2003 Evo VIII is pretty neutral. With properly tuned coilovers and the appropriate driving style, there's no reason why a track-prepped Evo should understeer.

No understeer...but a good deal of oversteer on exit....this car would be difficult for the average driver...but as they say, loose is fast, if you can catch it.

I don't ever seem to have too much understeer.... For me, it seems to be easily controllable by doing the following:
(Turn 1 at Road America)
Corner is a 80 or so degree to the right. Entry speed is around 60-80mph. Brake hard coming down from 145, start braking at marker #4. (#5 if you want to play a little safer). Get into 4th, just at about corner entry. As you turn in, lift off brake and apply a little throttle. Once you feel the car settle into the corner "groove", squeeze the throttle to 100%. The car then feels like it "pushes" the rear end of it through the corner, creating a touch of oversteer on corner exit.
There's been times I've lit all 4 coming out of a corner using this method, and I'm not pushing any crazy amounts of HP.

I also didnt have an understeer issues until I started driving 10/10ths. I want to make it clear that understeer in the evo sometimes doesnt show its ugly head until you start pushing the car past its limits.
all im trying to say is that evo's dont handle like that audi.... someone please prove me wrong by posting a video... I'm talking about corner exit push BTW.

Yes, I understeer all over the place with corner exit push and with late braking while trying to get every last millisecond of acceleration before the next corner. I guess I overdrive, but understeer is very apparent all the time with me, or at least it was at every event with the stock suspension.

adding 275 Hoosiers 1400kg springs in the rear and a 27mm rear swaybar will win time trails and be the fast car on the track... but it wont be as fast as a car that can rotate like that STaSIS audi.
I think we need to start getting creative
I'm going to try some crazy toe out front and rear ... maybe -1.30 F -1.20 R
