I have a full set of 30mm Z32 brake calipers for sale. They were rebuilt a few years ago(including the o-ring between the two halves) and work perfectly. They are painted burnt copper but have a few chips, however they still look good.
The calipers come with the hardware and SPL stainless conversion lines front/rear. They are currently mounted on the car so i will update the pictures once they are off and cleaned.
Not looking to separate at the moment
