Why mess with them? The only real purpose for spacers would be to clear brakes. The stock wheels already have that covered. Pushing the wheels out obviously puts you more at risk for rubbing the tires. That's why using the correct offset is important. IMHO save your money for a set of tires that are a bit wider than stock. In the meantime, enjoy it as is. Coming from someone who has owned eight Mustangs, don't change things just to change them.
BTW, what's wrong with the wheels? They look great on the Track Package.
