Keep in mind guys, the PFC Direct Drive rotors require the 7855 PFC pad fitment in the rear - due to the mounting hardware for the rotor ring.

And definitely try the PFC if you are a Hawk man - we were for about 6 years until we ran back to back. The difference is impressive and the consistency is awesome down to the end.
So the pad can't touch the first couple MM's on the rotor disc where it joins the hub, correct?

I have the UUC/Wilwood kit for my 330Ci which uses OEM M3 rotors. The pads leave about 3mm untouched from the inner edge of the disc.

So my question is, can I use these with my wilwood kit?

Do the DD rotors retain e-brake functionality?

Yes, the PFC DD rotors retain E-brake functionality.

If I remember correctly, it's not the friction material itself, but rather that the backing plate will hit the hardware when the pad gets ~50% worn. All the PFC pad shapes are listed in this document PFC catalog (7855 is at the bottom of pg. 93) if you want to compare measurements to the pads for your wilwoods. It would be cool if there was a wider range of pads to use with the rotors without modification.

EDIT: This page PFC/Pagid x-reference claims that the Pagid 2685 shape is compatible. I checked the drawing sheets for both, and there's a difference (PFC 49mm vs 58mm for the Pagid), but they are measured differently (distance from outer [farthest from hub] to inner [nearest to hub] edge of friction material at center of arc for PFC vs. what looks like distance from outer edge of backing plate at top of arc to inner edge of backing plate at either end of arc)

JamesC, can you weigh in? I know you guys recommend only PFC pads due to pad profile differences. Does this apply to this particular Pagid shape as well?

Two things:

-I do think PFC pads are the best and I would think people using their rotors would use their pads in some flavor. We don't carry Padgid and I haven't done the work on compatibility
-Material is an issue also. You need 2-3mm of unswept rotor ID statically. As the rotors expand with heat, the ID changes and pads running on the attachment tang portion is not good.

Thanks for the honest and candid answer.

I have PFC 06s for track now, so unlikely to need new pads for quite awhile.

i am looking to buy a set of either new or used pfc-06 or pfc-01's if anbody cares to sell them to me.

i have a set of z rated pfc's and they are just not cutting it for my "high speed use"..although they do work great for autox.

Hawk HT10's on my car for track days. They dust like crazy, & squeal up a storm, but they stop on a dime & give you 9 cents change. Talking from experience at LRP on Fri. I just love these pads. Chas.
