You might have some rubbing issues on the rear. The front will be the almost flush look.
aint too much you are going to gain with the fenders roll because of the tabs that are in it. I think 25 and 20 is optimal from experiece, I went 20 all around and it was almost like it need 25.
To check 1/4 panel/fender depth - Ride on level ground, weight suspended with a string off the very edge of the fenders - same side (check to make sure they are level) then measure same point from wheel hub to string. Not so Hi-tech but it works. Measure from rubber to lip edge when determining "flush".
