Thanks ...

Actually looking at Porsche themselves most of their racing efforts have been mid-engined
- GT1
- 917
- 908
- 956
etc.

I think only the 911 derivatives were rear engined race cars. And if you look at the mid-engined list above they were unbeatable in their time

With aerodynamic forces being highly important nowadays, it is importamt that he cars have a pinched rear and two much mass behind the rear wheels will not allow this.
