Maximum rim width for the Calibra without processing the wheel houses

Hello,I have a question for you Calibra driver I would like to buy my Calibra new wheels these have the size 7.5×17 ET 35 about the tire size I have not yet thought about.I would only be important to know if the rim size without processing the wheel houses still fits because a pulling of the wheel houses does not come into question for me also the edges I want to change.Maybe someone has experience with this rim size.Would I be very happy about helpful answers.
