According to the Porterfield website the AP45 part number (pelican # PMB-AP45R4-S) works for Front for PORSCHE: 78-89 911 and lists nothing for rear application. The part number AP31 on Porterfield (pelican # PMB-AP31R4-S HERE) lists for REARS FOR PORSCHE: 78-89 911. Hope this information helps.

What brake fluid do you run? I'd highly recommend trying out the Ate Typ200 fluid (706232-GOLD HERE). I run this fluid on the street and track and have never boiled it. It's cheap and works as anticipated. That fluid with SS lines will do wonders.

Let me know if you have any questions.

Thanks for clarifying the part numbers on the Porterfields.

I have 1L of that brake fluid I previously bought.
