As far as I know the slines are...but having an SE i've not bothered to look haha! If you consider I was supposed to be an SE, so 20mm higher, but my car is 5 years older, so i'm guessing it may have dropped a bit with some saggy springs no doubt. I dropped the front 50-55mm, so you're probably not too far out.
Eibach sportline (i think it's them ones) offer a lowering spring set that has a 50mm drop up front, and 40mm at the rear, to even out the front and rear. Or, you can consider something along the lines of what I have. Some 40mm springs and b5 perches would sit your car exactly where mine was, the difference is that your shocks will cope better as they're made for shorter springs. Each time I go over a speed bump I can almost feel my shocks wheezing, but they're holding up fine so far.
By the way, check out a google search of "audi a4 pinch bolt" and prepare to cry. Hopefully yours aren't as bad since it's a lot newer, but mine took over 6 hours to remove two bolts! They corrode into the wishbone so badly that you basically have to use any means necessary to remove them....oxycet and a massive hammer.
