Sadly I don't know that one, ask me what offset for a Subaru wheel and I'd be able to tell you and maybe that's the problem. I know Subaru owners and their cars get slated but they help each other out.

I learned so much about Subaru's whilst I was into them but since I've owned my Cosworth I haven't learned anywhere near as much because people keep their opinions/information to themselves with a few exceptions.
