Reasons? What makes you say it would look like crap? I can think of many cars that have had specialized body fabrication to accommodate mods and they still look good. Why would it drive worse? It sounds like you are speaking out of your as. So long as the work is done properly I don't foresee the car looking ugly and as far as performance and safety, Im still looking into that, so again if you have good reasons speak up and list them out.
