Pagid RS4-4 (Orange) for OEM B5 S4 Rear Caliper
Is there a Pagid Orange pad that fit the OEM B5 S4 rear caliper?
Maybe a better question, I am running 332 Stoptech w/Pagid Orange in front, and Axis Ult pads in the rear. I want to use the rears more with more bias, what is AWs MS forum recommendation on rear track pads? TIA...

no 4-4 available in the US that I know of, here are some options for rear pads:
Pagid is a solid pick, they offer these:
4-2 Blue
RS13 Yellow
The Yellow's are going to be tough to find, and cost you. Alternatives would be a Porterfield R4, more aggressive than a 4-2 rear or your 4-4 front, a Ferodo DS2500 or DS3000, both are more aggressive than your current rear setup, the 3000 will be more aggressive than the 4-4 Orange fronts. That's all I've tried for OEM B5 S4 rear options. In addition, I've never run the RS13 Yellow Pagid rears, but I know they exist.
I'd go with the Pagid 4-2 Blue for more rear pad than you have now, it should match well with the 4-4 Orange front. It can be noisy at times when cold, but it's not that bad.
I'd also consider a larger rear disc setup, I run the STaSIS 298mm Track Sport rear kit with Pagid 4-2 pads and I like the additional rear bias it gives me.

Thanks, once my rear rotors need replacing, bigger rotors will be on order.
After talking to Matt at Stoptech, I've got a set of Pagid 4-2 Blue coming to me. Thanks again for your inputs Ryan...

I believe the S4 S6 and S8 all use the same rear caliper, and ...
the S8's rear pad is Pagid Orange #1158 440 10; I have a set sitting in front of me on the table.
As Ryan said, the Ferodo DS2500 (FCP541H) and Ferodo DS3000 (FCP541R) are also possible depending on how much you want to shift bias to the rear. The DS2500 has a very flat 0.50 cf, the DS3000 a very flat 0.60 cf, and I believe the Axis Ultimate is down around 0.40 (but not sure). The chart below shows the coefficient of friction of several Pagid compounds.
