Hi Karl, I was actually talking to Ant about this today and yes they will all need cutting. Ill get as many pics of the whole process as i can and ill ask Ant to take pics when im not there. I would of thought so mate. Im not sure if standard wheels with these arches would look right. My wheels are 9" wide and sit flush with the arches so standard wheels with 60mm spacers would sit further in then mine will.
Im not sure on where ill get them from yet but ill put all updates on the build thread. Scott
