STI rear brembo's will fit you s-chassis if your running the Z32 rear drum assembly. You do NOT need to space it, it will fit perfectly fine with z32 rear rotors. I know this cause I have been running that setup for 3 years now with no issues. YES the e-brake will work as well with the STI rear brembo setup with the z32 rear drum assembly. Yes you need to change out the brake lines, you can run the z32 conversion brake lines which are sold everywhere. No one wants to run the evo/z33 rear brembo cause it doesn't bolt up and its too much of a PITA to get it to work. Most guys already verified that the Z32 rear caliper setup is actually better than the STI rear brembo due to more contact surface area with the brake pad. The brembo rear are only for bling factor. If you have the cash (which 95% of you don't) and can source brembos off a GT-R V-Spec (r32/33/34) it will bolt on as well (good luck trying to find affordable rear rotors tho).
If you want to go extreme and want bling factor you can run the DUAL z32 rear caliper setup which will use 1 pair as your ebrake (via hydro lever) and another as a reg brake caliper.

Theoretically you can use dual STI rear brembos or Skyline GTR brembos since they bolt up to the caliper ears the same way z32 calipers bolt up but I don't think anyone has had the $$$ to give it a try. But if your looking for the "BALLER" on a budget setup, that's one way to go.
