Hey Reece I filed my rim took me f**king ages about 15-20 min for each when your used to it.
I used a big file and a smaller one.
It isn't hard to keep them to same just go out to the side of each circles.
Saves a bit of weight and looks good.
Anyway got you some pics:
Looks nice.
Not too sure about the red rims though.
Ps: Try all rotors are really crap.
My back one cracked in 5 places but also when I changed it to a hope one I could feel a braking power increase.
