Personnally I'm just a fan of ground clearance...like being able to go over speedbumps, handle most standard drive grades, etc.:wink:
That and you as symmetrical of a gap around the tire as possible, IMO it looks like crap when the fender gap is say 2" on the sides of the tire, and 1/4" on the top
I'd rather have a big gap then a lop-sided one.
That said, in pictures the hieght looks good to me, if say the gap at the top wasy/is bigger then on the sides, then it would need a bit of lower.
