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.

> Well, I ordered four new SP 9000's and 2Bennett's camber/caster system. 
> ($O,uch)  I am very impressed by how beautifully made these plates are. 
> Installation was very easy. Thanks very much for the group purchase. That really helped. 
> Alignment with the 2 Bennet System yielded -0.8 deg Left and - 0.5 deg right,

> My thoughts:  If you're gonna' lower, you gotta' change the plates!
