I don�t know the SA versions. I have no diameter or caliper measurements for
the SA version.
The Audi caliper is single piston and the rotor 288x25mm.
But with my adapters you can mount the bigger Audi A6 brake versions, also.
Up to the S6plus-Versions (300hp V8)with two piston calipers and 323x30mm
rotors.

Perhaps the S8 and RS4 brakes will also fit (360x32mm), but I am not sure.

I am doing the conversion on my 2WD and use a new hub, too.

The rotor is not vented. Yes, the hub has to be machined smaller.

>OK, one last question. How are you adjusting front to rear brake bias?

No ideas yet...
First I will complete the rear adapters.
But: The brakes dimensions are exactly the same than on the Audi (245x10mm
on the back). And the Oettinger WBX6-Versions of the Vanagon also use these
dimensions. They havn�t modified the bias at all, so I would think the stock
bias configuration works.

>Part numbers would be helpful, if you don't mind.

I have no part numbers yet (perhaps some parts have to be exchanged in the
process?!)
These parts were lying around in my garage, so I tried to use what I got.
