I too have just lowered my 96 S6 with Eibachs/Bilstein. My car has dropped
20mm front and back tho back has 10mm spacer. I maintained the original
camber plates. Camber after alignment is -1.3 left and -1.5 right. I was
told spec is -1.3 to -0.4 - I'd point you to the ECS Tuning link that shows
this but I don't have it on my office PC.
I will keep an eye on the inside edges for wear.
