For those interested, from what I gathered, it's possible to run Mazda6 brakes with the GTR spindles. You can use either the smaller 11" discs found on the early 6 and base 3, medium 11.8" found on the 3 GT or 5 and the MS6 12.8 discs from the speed6. You need the discs and the caliper brackets, the calipers are apparently the same.
If anyone has access to these parts live to compare, please do.
