So I stole this from another ZX2 site, just a heads up. I just wanted to make sure this information stays available.
You can still purchase a couple of S/R parts. All of the parts for the rear disc brakes are available. As a matter of fact, the rear disc brakes actually came on the 97 Escort sedan (which is where I got them from). As far as the special parts, the car was a colaboration between SEMA and Ford. Most of that stuff that would be deemed necessary is still carried by Ford Racing (struts and springs for example). The cluster is not, because the stock 120 cluster can be used as a replacement. I did come across, however a 150 MPH repair kit, which the parts counter could not explain what it was.
Here is a list of part numbers that I compiled, containing almost all of the parts unique to the S/R that I could find. I just verified these numbers still do exist via oemfordparts.com and fordracingparts.com. I don’t have the luxury of obtaining true availability, unless I bother my parts guy (which I’m not):
