Your fron 17x7 wheels are et55, same as mine. My rears are Boxster, 8.5" wide et50. I don't know what the offset of a 9" wheel is. As far as I know, all 911's got a 17x9" wheel out back.

You're going to need to space these wheels out quite a bit to clear your struts, so you could factor that into your adapter setup, but I don't know of any 4x130 to 5x130 adapter that also spaces out over and inch. Maybe you can get something custom made?

If you get 5x130 drums all around, then you just need to space the wheels to clear everything, front and back.


This is a little off topic, but are you the same guy that asked this question about a month ago, and that I gave the same answer to? The similarities are too great to ignore.
