Interesting...Did a quick scan of an article (in EC) comparing 6 996tt's.
I looked at all the braking stuff (distances, tires, brake size). The worst stopping distances were provided by "upgrading" to a 15" rotor and 8 piston caliper. The best stopping was done with factory PCCB parts and Michelin Pilot slicks on a Cabrio, while 2nd best was done with a full 15"/14" F/R setup on Hoosier race slicks (2' longer than the Cabrio).
As it has been said before, bigger isn't always better, and tires have a WHOLE lot to do with stopping ability. I have a feeling the people running non-factory brakes were invoking ABS much sooner, which resulted in longer stops. The "gumball" tires were only found on a couple cars, the others wore Yoke or Michelin UHP street tires.
But, I will say with ABS switched off on our cars, bigger brakes can be modulated easier, have a much higher thermal capacity (Fade? Was ist das?), and work much better at higher speeds. I'll also say that the rear brake size, IMO, is well suited for the 11" G60 setup, but a 12" setup I start to get the feeling that the 9.4" rotor and single piston caliper is too small. Which is why I am looking at B5-S4 rear calipers and B3-90 rotors hung out back. Roommate is also looking at what to do for rears when he bolts up the 13" setup.

nice.. good hunting Koop. I think the answer to the rears is simply to move a front brake-kit of...
a similar car (i.e. B3, S4, 100, etc.) Don't both tryin' to go fancy with any aftermarket rear kits....leave that for the front.
So you're still leaning towards front B3 rotors w/S4 front calipers (G60's I presume)? sounds good...
check yah later

No, B3 front rotor (256x22) with B5-S4 rear caliper. I need a little more info on the rear rotor of the B5-S4 though, and compare that to the B3's front, make sure the offset is the same, or if I can work something out easily...

Re: Koop, if you do go that setup, will you have parking brakes?
The B5-S4 brakes are rear brakes, with the same type of e-brake mechanism found on our calipers. So yes, I would have an e-brake.
Roommates car may or may not end up with an e-brake. He may go all the way to the 276x25 rotor, which would not have an e-brake due to it using a G60 caliper.

Similar to what I said WRT big brakes on street cars...There is a definate effective upper limit for
street cars, running street tires, and being useable and an actual improvement over stock...
