I'm working on the theory that the shocks will likely benefit from a change soon, and if I'm doing that may as well do the springs
the first choice in my head is Bilsteins. So I've been doing some digging and thought I'd share
Mines a 2002 S8 so if I understand correctly;
S8 is 25mm lower than corresponding A8?
Eibach lowering springs are circa 25mm lowering on an A8 so can be interchanged with the S8 on standard Sachs shocks or replacement Billies?
Part number is E1533-140

Bilstein do a B12 kit for the D2, which according to their website is a package deal of the Eibach springs and B8 dampers. B8 being B6 spec but shorter to allow for the drop.
That said I can find B6 shocks listed but not B8, so I wonder what's in the kit?

I've emailed Bilstein to try and find out what's in the B12 kit exactly.
In the mean time any thoughts on the above appreciated.
