[s-cars] Tire Wear - Lowered S6

[Fred Munro]

The front camber alignment spec for the UrS4 (from the alignment machine
printout at my local dealer) is -1.08 to -0.08. Caster is +0.25 to +1.58 and
toe is +0.04 to +0.17

The inside shoulders of my tires were wearing at a camber of -1.04 with the
stock suspension.

Eric,

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.
