less wide.
I mounted the STI caliper onto a complete Z32 rear conversion and what do you know, It fits PERFECTLY! no need for a spacer for the mounting holes.
The pad covers the rotors surface perfectly and centers perfectly.....
Now that I found a working solution which keeps the e-brake from the Z32 and uses the Z32 rotor, I just need to get new pads and some braided rear lines and voila! a complete STI caliper conversion with front evo rotors+pads and Z32 rear rotor with a functional E-brake.

I was looking through this as well and have an alternative solution. If the Z32 rotors work, that means the ideal hat height is 63mm (height of Z32 rotor). The rear GT-R (any with factory brembos) use a 300mm x 22mm rotor with the same hat height. This rotor is the same dimensions as the EVO rotor except that it has the correct hat height and uses a Nissan sized internal drum. I'll be getting my rear STI brembos in the mail soon, and I'll test this out for sure. GT-R rotors are a little harder to get, but they're the right width.
