17" versus 14" tires

I honestly prefer the look of 15's but I can't find a 15" torque thrust style rim that I like that has the backspacing I need to fit the tires under the car how I would like. I should say I can't find any that I'm willing to pay the price for. With 17's, it seems easier to keep the fronts away from the fenders and still end up with a decent tread width. Torque-thrusts have always been my favorite wheel and I'm looking at the 17" Mustang "Bullitts" as a substitute.
