um...no offense are you going for an aggressive look or a function??

if your going for function and your plan on wheeling, most likely you will scuff up your bottoms of your cladding anyhow...when i did my trimming it was a triangle only 2x2" probably, not much compared to the chunks missing from offroading...

just saying that if your going to wheel, trimming really isnt a big deal, its probably the least of your worries...

if its aesthetic, then the only way is to change your rims...or use spacers

you can achieve a little through wider tires but not what your looking for...
