I kid you not, but to reduce unsprung rotating weight ...
My brake rotors were bolted to aluminum hats with 48 steel bolts. I replaced them all with titanium fastners. Titanium is about 55% the weight of steel and, with the proper alloy, about as strong as a Grade 8 fasteners. [Aluminum is even lighter than titanium, but only ~1/5th as strong.]

Any idea how your current rotor weight compares to stock S8?
Are you running an Alcon setup now? I'm too lazy to check archives today.
I came to a similar conclusion that most reasonable price D2 S8 enhancements tie to weight reduction: unsprung = wheels, tires, brake componets; and sprung weight = auto/electro/luxo gizmos, spare wheel/tire, and driver weight : )
Trouble is, I don't know what luxury items I'd be willing to delete from the car, so I'll focus on unsprung & driver weight reductions.

10 lb/corner savings in the front, 5 lb/corner in the rear
A 30 lb savings in unsprung rotating weight is huge. You'd need to go to ceramic rotors to do any better (and ceramic rotors are <i>much</i> better).
The stock cast iron rotors, especially the front's, are very heavy. And yes, I'm using a one-of-a-kind Alcon front setup and a <a href="http://www.stasisengineering.com/Category_Detail.aspx?id=8&YR=2001&MK=Audi&EN=51&PI D=47">Stasis Rear S4 Kit</a>.

Don't know of any off-the-shelf alternatives today, but ....
Making a <a href="http://www.hrpworld.com/index.cfm?form_prod_id=163,164,49,363_1521&action= product">Custom Aluminum Hat</a> for the S8's 345x30mm disc isn't difficult, the trick is finding the disc itself. The closest I've found is a 343x28 Alcon or a 350x28 Brembo, both from <a href="http://www.hrpworld.com/index.cfm?form_cat_id=163,164,49,363&action=catego ry">Hoerr Racing</a>. A one-time expenditure for a custom hat isn't too big a deal, but you certainly don't want to be buying custom discs every time a set wears out. [BTW: I've never measured an S8 rotor. Is it really 345x32 as the Audiworld Resource guide says?]
You might also call Stasis and see if they'd be interested ... there's obviously a market. You might also remind them that their S4 rear kit works great on an S8. Stasis doesn't list it as an application on their web site.
