The rear fitment will be tight. We have not tested this combo. There's a good chance it would clear by a few millimeters, but a roll may be needed. We have a local customer with a non-m. The next time they are by the shop, we will test this fitment.

My only concern is they are half an inch wider than stock of 17x8. Will that stretch the 225's a little? Would it be better to run a 235 on this wheel setup?
17x8.5" ET40 with 235/40/17 is a very, very easy fit. Even 245/40/17 is an easy fit front and rear.
The most conservative setup I would run on the non-m Z4 is 245's on 17x8.5's.
