i dont fancy moving the screw because its stopping the wheel hitting the edge of the wheel arch surely? haveing the screw there means that the tyre cant come into contact with the bodywork
Well, since the screw is connected to the bodywork, any impact on the screw will be the same as an impact on the bodywork if deformation is your concern.
I have removed the screws on mine as the tyre was hitting them on big bumps. I have bent the metal versy slightly inwards and tucked the plastic arch behind it out of the way. You can't see any changes unless you stick your head under the arch. The advantage of this is there is easily another 5mm of space under the arch for wheels and the plastic inner arch is just as secure once tucked up behing the metal lip.
No more rubbing for me
(My wheels are 18x8 ET45 for reference)
