Big Brake ?'s
I've searched and haven't found the answers I'm looking for.
1. For fronts, can the stock Cayenne rotors be used with the stock Cayenne calipers on AR?
2. For 993TT calipers, does anybody make a bracket to use on AR? If so, with what size rotors (specific vehicle?)?

I believe the rotor possibilities are:
B5 S4\allroad 321x30mm
Euro S8 323x30mm
Porsche rotor rings with special hats 323x32
Mercedes Benz V12 320x30.
Monitor the forum for Trango's results. His Budget BBK solution may be better for those running 18" or larger wheels.

I'm going to use a different rotor...
...and I'm currently deep into another project, meaning that although the wheels/brakes/etc are moving towards the front of the garage, they are not to the front yet. The cool part about this other project is that I found a pair of desert racing coilovers for the buggy for $500... 16" travel sway a ways, with not exactly the right springs, but close. Making mounts for them probably this weekend, and the final iteration of the new suspension is so flexy that I had to put a pillow block/bearing into the front driveshaft to get it to clear the crossmember. So, more BS upon more BS. 
I'd guess that I am looking at a, well, probably a June-ish timeframe to do all the measuring and fitment of this solution. I don't foresee any other project coming up, although one may never be sure.
Flattered by the reference, for sure.

Oh yeah - both ?D5? (early 2000's S8) and B6S4, both have 345mm....
...to add to the alphanumeric soup of models that have suitable rotors. Well, suitable in that they have the correct diameter.... they still won't fit on the allroad's hub, with the right spacing for the caliper to bolt on. Well, I'm actually not 100% sure about the S4 rotor.
And, what I'm really going to shoot to create here is a formula, that you can use to create your own BBK, and take out the "black art" factor of BBK's in general. Brakes are stupid easy - it's a matter of measurement, fitment, and enough poring over catalogs and opening up boxes. When enough people do these activities, with whatever motorsport aficionado subject at hand, you get... a corpus of knowledge that serves to spawn grassroots innovation.
Enough editorializing - full on burgers and beer = fat and happy, and apparently verbose.

Nope. These are possibilites for the 993TT caliper. ECS tuning and 2Bennett Audimotive
currently supply Cayenne caliper based packages and Trango is working on a lower cost solution.
