^^ oh yeh ; have you seen where they are rubbing on ? Might only be the bumper-bracket ? If this is the case then the bracket can also be bend/modified/grinded .
When checking this (rubbing spot) you will see it is the ONLY place where rubbing is possible because there's loads of space in the wheelarch; except for the bracket sticking out ! When sitting in front of the wheel , feel along the arch/screen and it will be on the top left (passenger side this case)
If you're not silly low, this is i think your rubbing prob.
