The S4 is at Achtuning in Redmond, WA getting aligned today. If you are in the Seattle, WA area, I highly recommend them for alignements. They are the best in my opinion.
Also I did make some adjustments to the ride height. Fronts are at 25.5in fender to ground and rears are 25.75in (F2G). There is a little rubbing in the front, but I have to be going around corners hard. I might roll the front fenders in the coming months as I do have a fender roller.
