Keep in mind that you do not need or really want to invest in cross drilled rotors for the rear of the car. That is unless you are into the bling/show scene. The practical reality is that you are doing a full conversion and the rotors and calipers will come from the 93. Up front I stayed stock on our 89. The difference for me was the meatier (thick) Brembo rotors and a set of AEM/Nissin pads. Work fine for track days. Race setup is more agressive.
