Glen,
I don't know what the deal is.
The club sport calipers from the 968 only differ from "base" 968 in
that they have bigger pistons in them. They appearantly use different
pads that I am not familiar with but assume them to be two friction
"pucks" bonded to a single backing plate. I don't see this as a
significant draw back (maybe missing something?), it will reduce the
surface area of the pads slightly but will at the same time increase
the PSI on the surface of the pads. I am quite impressed with the
calipers in question, they each have 2-36mm dia. pistons and 2-44mm
dia. pistons with the smaller pistons on the leading end of the caliper
to reduce the taper wear of the pads. Being a fixed caliper there are
less prone to binding as there is no floating caliper frame to stick or
bushings to wear or get gummed up with road grime.They are also lighter
than the cast steel calipers and "look cool". I don't think that Audi's
have a problem, in general, with brakeing ability and the Audi calipers
I have dealt with over the years have not been troublesome. I am not
sure I would spend the money to convert an Audi over to these but they
are very good brakes. These are the same basic caliper as Porsche is
using on the 1996 911 Carrera's today and used on the 928 GT. I have
done several upgades of older Porsche's to these brakes and they are
well worth the money for this type of application.
