PFC rear brake upgrade

For those who have replaced your rear brake system with the PFC 12" kit that the Grand-Am/Continental cars ran, can you tell me the vendors who sell the kit and what the cost wasfor the complete set-up? I have seen posts that indicated Kohr sells the kit. Is that the only option?

ArizonaBOSS, thanks for the link. Now that I think of it, I saw this stuff before on FTB's site when I was bored and surfing the web for ideas. I have the Blowfish aluminum brackets now with a 13" GT500 rotor and stock calipers. I was having a weird issue with the original caliper pistons seeming to contact the pad too high (touching the spring) causing the pad to compress at an angle. Couldn't see why other than the bracket but I traded the stock calipers at AutoZone and it seemed to fix the issue. But now the rebuilt calipers from AZ are rusty and look horrible. I thought the PFC calipers were a better single-piston design and aluminum? I can either paint the existing calipers (i'm lazy so PITA) or upgrade but I wanted to know just how costly the PFC kit was first.

IMO, I would only use OEM Ford rear replacement calipers

I see that now......my calipers look like crap. Since I already have the brackets I might as well go with new coated OEM calipers and some nice two-piece rotors. That FTB kit is pretty nice so it looks like that's my best option.

The angular wear that you mentioned was probably caused by the caliper bridge bending either through fatigue or a combination of heat plus fatigue. You have to replace them every so often. Kind of sucks but it's cheaper than a $4K radial mount setup.
