One of the things we always ask in the morning at the Evo schools is "How many of you think your car understeers?" We ask the same question at the end of the day and get a lot fewer people raising their hand. I agree with Bren's assessment, you might be standing the car on its nose and snapping the throttle open which can cause oversteer. Or it could be as simple as you're not unwinding the wheel. Do you have any video?

Positive toe on the alignment sheet is toe-in. Negative is toe-out. So you have about 1/8" of total rear toe-in, which doesn't sound excessive to me, but I like to run as close to zero toe in the rear as I can get away with. Now, more rear toe-out will make the car looser on corner exit and in transitions but theoretically the car will slalom faster like that. I like to be able to hammer on the car through slaloms and not have it come around on me. If I can't do that, I'll make shock changes until I can.

Look up some shock dyno curves for your shocks and see what the rebound curves look like at full stiff versus full soft. I don't remember how single-adjustable Koni curves look.
