I'm trying to sort out the right rear suspension of my 2003 Z06. It was hit real light in the back right corner. The right side muffler took the brunt of the hit and was pushed into the right rear wheel. It did no damage to the rim or the tire. But, it did twist the wheel so that it looked as if it was turning towards the left. Here's a picture, which may be worth a few words, or so.....

I visually inspected the suspension parts and I can see no damage anywhere, either to the parts or where they attach to the passenger-side main frame rail and rear carriage. As you can probably see from the picture above, the bumper beam was only marginally displaced - it was bent forward slightly, but only after where it joins the main frame rail. The main frame rail shows no damage or effects, anywhere. Even the very end of the bumper beam
is not damaged and I was able to pull it back into a straight line.

I adjusted the toe-rod to bring the wheel back out, so that it's not turning inward. However, when I take measurement of the wheelbase from one side to the other, the hit side appears to be 1/4" shorter. Now, I haven't brought it to be aligned, yet. Perhaps, my toe adjustment is not even close (it looks relatively the same as the other side) but I'm just curious if anyone has any numbers/measurement of the rear suspension geometry. I figure that the only things that could be bent are: the spindle knuckle, upper and lower ball joints (is the upper joint just pressed-in, and is it serviceable?), or the A-arms (I'm skeptical that they are bent but the lower one doesn't look as robust, design-wise, as the upper one which has substantial webbing between the two arms). Believe me, the frame rail and where the control arms attach to it, still look like new.

Ideally, someone has the geometry measurements I'm looking for as I don't want to start replacing parts before I know exactly what I need.
