Front backspace 17*8 on dart, final advice before buying

Went ahead and measured roughly at ride height today again this time taking pictures. Height is for a 235 45 17 tire and I made the width 240mm total, ie. 120mm out from either side of the cardboard "disc".
It clears the sway bar, tie rod etc but close on the inner fender.
What does this tell me? Possible if I trim the outer fender or not possible?
