I got both the 260mm and 280mm calipers and brakes from wrecking/reconditioning yards. It was a pretty hard search though.
The price wasn't cheap either the 260 were 50 bucks each, and could use rebuilding, the 280s were 150 each but all ready to install.
I might sell the 260s just got to clean them up in my blast cabinet first.
The Mazda3 is different from what I could see but maybe the entire spindle/caliper/hub/rotor could be used from the 3. The spindle pattern
Easiest to just locate some Ford Focus brackets, the yards are starting to
know that Ford stopped making
them as their prices were double what they were 2 months ago. Not sure why
Ford would do that, I once read that automakers were obligated by law to make
parts for 15 years after a car Model was discontinued...?
Hope this helps somebody,
