Re: AP 6 Pot Brakes

I've had JFZ XL 150 4 piston aluminum calipers on a 914 w/ 911 S struts and
911 Carrera rotors. Calipers were extremely light, pistons were all 1.5" in
diameter (even available in titanium), a single large cotter pin was used to
hold in the huge pads (of the carbon kevlar variety), no dust boots. Light,
flexible (bad), and not too great for the street (thanks to the pad
retention system (noisy).

Conversely the Big Reds for the S4 are a street caliper (don't think they
have dust boots either though? Do fixed calipers have these?), albeit mucho
grande. They also have the slickest pad retention system I've seen,
staggered piston diameter, are still lightweight (although they seem much
more substantial from a flex standpoint). They are not on yet but within the
next two weeks!!

Which makes for a great segue to my question about brake pads. I wanted to
find the same pads for my S4 hybrid application Big Red calipers front,
stock brakes rear? What's the word on different compounds front & rear? I
was searching for the same pagids front & rear but I have been thwarted to
date. Andersen Bro's only has Pagids for the stock fronts.

I've been able to find similar f & r pads from Rofren as well as Hawk. Any
BTDTs with these brands? Questions, comments, suggestions? Thanks.
