As Joe mentioned, since 2012 I have offered a 13" brake kit for the 88s that allows you to retain the stock 88 calipers, parking brake, and brake bias for $750 shipped in the US.

I also have been putting miles on the same rear kit, but with Brembo calipers that are a hydraulic match for the 88 calipers and front rotors to match the Brembos. It also works great, but quite spendy:

I also have other parts for the 88 Fiero on my website:
