cut the inner lip or the outer lip? The inner lip/ L is structural as you know, the outer lip is an indent for the outer lip. also semi structural.
If your forming them by hand, that lip gets contorted very easily. (I played around with keeping it or not myself when I was forming the flares) and IMHO it dates the car. I dont think he'll cut them off more as hammering them flat (the inner lip can NOT be rolled in, he'll have to bend the metal back, as I had to do this on felix's fenders when I was attempting to work them.) The problem I faced with my OLD fenders on my car was I went back and forth with the lip too many times and the metal was separating. Partly the reason why I told felix the flares were not good enough for his car. also why I went with fiberglass.
The rears will need 1.5 inches. but thats pretty easy if he's got a palm nailer and he's done that before. the fronts I think an inch will be ok, but the problem will be lack of clearance when in turns.. Which I believe is one of the reasons JP cut his fenders up higher.
Im sure I've told you all this before, but heres a post to jog your memory!
oh ya.. Drool sucker!!!
