Hap,
 
I feel that your brake analysis is flawed. I track my car quite a bit and  
run 343X32mm 2 piece AP racing rotors with their 6 piston calipers. They fit

under my 17" OZs and SSR Comps and I don't experience excessive front end
dive. 
I run stock size slotted rotors from ECS on the rear. I have found that by  
running the rear rotors without the splash shields, they run cool enough to

use Hawk HP Plus pads. I can also run Hawk HP Plus pads in the front for
tracks  
like Lime Rock, that don't require a tremendous amount of braking. Tracks 
like  Watkins Glen require a more track dedicated compound if you run in
multiple 
run  groups, which I do. There is not enough time for the brakes to cool 
down. This  could probably be resolved with cooling ducts, but that is
another 
issue.
 
I also run the 2Bennett coilovers with 400lb springs, both front and  rear. 
However, I run the Advanced Design front struts. I run these at  minimum 
compression and only 1/2 turn of rebound for both the street and track.  The
rears 
are Koni Sports at maximum rebound. I intend to have my Bilstein  Sports 
revalved and swapped in the place of the Koni's this winter. I also  run a
28mm FSB 
and your 26mm RSB on the middle setting.
 
I think a good solution for the rear would be a larger rotor with a bracket

to offset the existing caliper. However, at this time I don't know if that 
would  be useful without some way of changing the existing brake balance.
 
Regards,

I flogge...  er...  um, 'drove' Robert's car (post Mihneaificationified)
recently...  

...while it squeaked and squealed like a stuck pig from just about every
orifice (quasidedicatedtrackslut syndrome?  I kinda dug it, esp. pulling
into the store lot), manohman, man did that car brake like crazy and feel so
right dynamically.  Wish I had some 9/10 time with that set up but that will
have to wait for another day heh heh.  Can only imagine that what little I
felt goes a very long way.

Those 6 piston AP calipers feel da bomb (pun intended).  And them rotors are
stunningly ohmyholymoses large.  Look fab under the Super Leggs, BTW.  This
set up exhibited no where near as much brake dive as my 993tt front / A8L
rear rotor mit mintex set up does with 29771 / Bilsteins.  Thinking that
Bilstein revalve is looking more and more appealing, esp. after driving Neil
Swanson's mit revalved ones, prob has good amount to do with it.  And up to
this point I thought my pedal feel was for some reason one of the best I've
felt in big brake set ups around these parts...  not anymore.  6 piston
Alcon's...  wow.

Again, no idea on 9/10's + effectiveness, but thought I'd share impressions.

'95 //S6 needing new front pads soon meself / no Alcons / No revalving in
its future / only baby seats

ps.  dare someone to toy with rear brackets as Robert blazonly suggested...
be an interesting (read: budget) option.  Lotsa of you crazed engineers out
there and all...
