I have 17x8 ET35 with 215/40R17 on my 4x4. The front and rear arches have been rolled and don't catch. But I think they would catch if the wheels would be ET25. Of course it also depends on the tyre size, but with 8J wheels 215 is already a quite narrow tyre. In my opinion ET25 doesn't look right either, it seems like the front wheels stick out.
With the 6 degree beam the rear wheels move more straight up and this makes the clearance even less. This is with the suspension arm on the bump stop.
