I am definitely interested in the mazda6 calipers as well! However, I am confused on which way to go. Used on here, or remanufactured on Rock Auto? No offense to you 95blkprobe, but I can get each caliper and all the hardware for around 45 bucks each in like new condition. Why would I buy yours if they have been used for a while? Once again, not picking any fights, just curious on what the difference would be as I don't really know what makes a difference.
