I don't know what the issue is...
I would say frame flex; I've seen that on a lot of cars... That were making a ton of horsepower.
I've seen a car twist itself in half at ~1200 hp.
Dude could not weld, lol.
The only thing I can think of that would cause that otherwise is a really loose unibody. Something is twisting up to move the wheel like that.
Do you have any braces? I'd look to see if the mounts are moving around, or if any of the more common areas are cracked. (IIRC, the firewall above the tranny and the area behind the driver are pretty common.)
You know, you mentioned having konis; if the rebound damping is too high, you can pick a wheel up pretty easily. Take it to a big deserted parking lot and adjust on it, see if it changes. More important, make sure they are set the same on both front wheels.
