I'm currently using stock factory calipers... pin-type... with Cordoba 11.75 rotors, as well as steel braided lines. For many past years ... 1970s- 80s (before I swapped to the Cordoba rotors and braided lines), I ran full organic Wagner front pads... the car was then dominantly used for SCCA pylon autocrossing. The full organic pads worked great with only minimal runs.

Later on, I switched to semi-metallic Wagner pads (same as police pads) ... being old-time asbestos material (now obsolete for health reasons)... and they worked pretty good for extended time on the autocross courses, very good on the street/highway, and pretty good on some hi-speed road course time trials (but... they were very dusty upon heavy usage). I recently used up my 2nd remaining old set of those same asbestos semi-metallics... more usage on HSAX/HPDE events, as well as more on the pylon autocross.

I briefly/recently tried a cheap set of O'Reilly standard semi-metallic pads... those didn't last long at all ... one weekend at a HSAX/HPDE session... not good stopping power, either.

I've just put on a set of HAWK+ front pads... I forget which number (bought from Summit)... about $60/set?... and there is an absolute improvement that's noticeable... for all driving and performance events.... and they are cleaner, too!.... I bought two sets... They wore well through one full day of HSAX/HPDE... should be able to get a couple more weekends or longer with them on HSAX/HPDE. I'll use these for the next season or so... maybe I'll eventually try the yellow or red brands.

Regarding FF pads, I believe they are simply re-boxed .... from Wagner... should be A-OK/good ... nothing to worry about.
