Pardon my ignorance, but what exactly is rolling the fender?
In the inner fender / wheel well area, there is a lip that sticks out. This does not touch the tire based on OEM setup.
But because tuners / modders love the drop (lowering the car), and adding bigger rims and in my case, maximum tire size to fill up the wheel well, then you get "rubbing".
To solve this, but not a guaranteed solution, is to roll the fender which if I'm not mistaken will give you no more than an extra inch of space in the well. A special tool is used to roll the fender, basically pressing that inner lip against the inner wall fender so the lip no longer sticks out. Some shops do it properly, some do not. And as frolf mentioned, if the shop is careless or inexperienced in rolling fenders, they will crack the paint.
Usually the cost to roll a fender is about $60-80 p/ fender. here in Toronto its about $80CAD p/fender.
Hope that wasn't too confusing.
