Different method of cutting arch

[vrooom]

Im about to fit 13x7" superlite (dont like that much but got it really cheap) and group 5 euro arch

i only know 2 method to cut the front arch to clear the wheels.

first one is folding the arch upward and cut the excess out.

second is cut the arch as it is, then hammer the outer line to L shape.

Do you know any other way to cut the arches ?

also what is wheel sizes that look good under Group 5 euro arch ? I quite fancy that Mamba alley cat rim. look sexy
