S4 brakes? Wilwood Quality

[Daniel Harman <dharman@sprynet.com>]

I know that the S4 and TTs both use new 12.8" 2 piston brakes. Aren't
two pistons a low number for such high performance brakes? How do they
provide so much stopping power? Will they be available for aftermarket
(i.e. for an A4.)

Also, if you read European Car or MaxSpeed you have seen RPI's A4. It is
a lot like mine, and I was impressed by the brakes it is equipped with.
They sell for $800 and include:

-2 Brembo 11" Drilled Rotors
-2 Goodridge Brake Lines
-2 Metal-Matrix (or Carbon-Metalic, I forget which) Pads
-2 Wilwood 4 piston calipers

To me that seems pretty cheap concidering RPI's prices.

200 for the discs
100 for the lines
150 for the pads

That leaves 350 for the calipers, isn't that rather inexpensive for
calipers? I haven't heard much about Wilwood's, are they any good? Would
you think this to be a suitable package for an A4?

Thanks again,

PS. I know I wrote three messages in a few minutes, but it is raining
and with not much else to do,  I am trying to get my upgrades in order.
Please forgive my lack of knowledge and a life (while it's raining that
is...)
