Bent suspension Piece FR IS350

[zooland]

I whacked the front right wheel of my car (IS350 Factory Sport Tuned Suspension) into a median pretty hard on the way home from christmas party last year (going around a curve and did not turn in time). I knew i screwed something up because the wear on that tire was drastically different than that of the others (it had worn to the cords on the very inside of the tire) I told the lexus dealer that i thought something was up but they said everything was fine....I took it to a body shop and they measured the frame and it all came out ok. The car does align within specs but I know that something is still F'ed up.....every time i get around 80 there is a slight shimmy and that same tire (front right) is cupping on the inside again. any ideas as to what I may have just slightly screwed up to cause this? Any help would be greatly appreciated.
