The rears will (very very likely) rub. Also most likely on the driversside. The fronts, i do not know. I have 18*8 ET35 with the same tyresize. They are ok. The 8J rim is a better fit for the tyre. The 8.5J streches the tyre too much.
Thanks Flyingdutchie ,i have decided to not bother with them , too much much messing around ,shame as they were very nice light carbon wheels. I will have to limit my search to 9's on the rear.
Experiences are a bit different though. Some have rubbing issues with 9J also. I have 9J at the rear and 8 at the fronts. Offset is 35mm. Mine rubbed at driverside at the rear. Productiontolerances matter. Ridehight can help also. You have to try it.
