I have not measured my sway bar links on the rear but started out the same length and adjusted them the same when I was finding that happy spot between long enough to not hit the upper adjustable MikeR camber arm and short enough to not hit the body seam of the car (I had to grind the body seam to allow clearance). The rear sway bar bushings are not even a year old and replaced with energy suspension urethane ones.

I find it inetersting that your sway bar links are different lengths. I never thought about measuring front wheel to back wheel or to double check the centering of the rear wheels.

You think it is something with the rear suspension?

I do notice a little shimmy when immediately letting off a hard throttle.

I am wondering if lowering as much as I did really messed up the handling?
