Just lowered my '15 DSG Autobahn on ST XTA Coilovers. Still getting the ride heights dialed in, trying to resist the temptation to dump it. Currently sitting around 25 1/8" FTG all around. 225/40/18 on 18x8.5 +35 Konig Kilograms.
Running 6 clicks from full stiff front, 5 clicks from full stiff rear. You have to remove the rear shocks to adjust the rebound, fronts can be done with a small Allen wrench. You can't adjust the camber plates on the car without cutting the strut tower opening. Planning on possibly doing this in the coming months. Height adjustment is simple in front, don't have to remove the wheels if you're not slamming it. The rears, not so simple, as the spring perch spins while trying to adjust the height (these only use one spanner wrench), so you may have to remove them to adjust height too, making this a pain.
The ride is firm but well controlled at my current settings, haven't tried anything else yet, as it's a pain to adjust the rears. If I had to do it again, I would probably go 9-10 clicks from stiff front, and 8 in the rear.
