i've heard that too much rear camber will hamper the car's ability to rotate, ie it will understeer more with too much rear negative camber. & all of the companies you listed recommend 0 camber in the rear. let me/us know how it works for you as one of these days' i'll be getting an autox alignment on my RS.

 

I ended up with -1.5 degrees negative camber up front and -1 degrees in the rear. So far from initial impressions I like it alot. Very smooth and neutral in corners. I'll see how it ends up during the week.

 

Running the same on my little civic with a little toe out up front. Been about six months now and no abnormal tire wear.
