teh_mechanic hit it on the head. I have the koni's on stiffest setting because of the scrub issue. I had it on sports setting(which i believe is middle turn) and with just me in the car, no scrub... Once i had a passenger it was burrrrr. Put it on stiffest, i can get 4 ppl in the car before it starts to burrr.

The only other time it will start scrubbing as you said is it really uneven roads and while turning hard. But the koni's have definately helped my scrubbing issue
