Help me decide - Big or small bolt pattern?

Most people who convert to big bolt pattern do it for better wheel choice. If you have wheels you like, in small bolt pattern, why change? I would get dimensions from your front wheels (width, backspace, and center hole diameter,) and call Dr Diff, find out if his small bolt pattern disc kit will work.
Edit: you might want to consider going to 15" front wheels/tires. 14s are going the way of the dodo.
