cutting wheel well a must?

[spools420a]

Hey all I have some ugly body damage on both sides of my rear quarter panels on my s13 and was thinking it would hide those very well with a wide body but on the other hand I dont want to hack up the wheel wells,My question is if I was to get like 25mm or some small MM diameter widebody is it a must to hack the wheel well or can I skip this procedure and still look great?Likw I stated I dont want to go very wide just the minimum to cover the ouches while enhancing the looks thank you.
