I just scored the rear beam from a 3rd gen SE hatch with the intentions of trying it on the 2ZR Vios. Feedback from the resident SCCA Club guy (Jason@Sportcar) is that the stock setup doesn't benefit from rear discs since most of the braking is up front anyway, and the OEM rear balance isn't set up for discs. The speed you'd carry into a corner with 200+ whp may change the need for them though. In theory I'll see if it fits over this winter and (hopefully) document it. The pads themselves are TINY, even by subcompact car standards. I haven't looked at other options for bigger calipers or rotors yet, but that's worth investigating.
