Just as soon as we spend the money to buy a car our immediate reaction is: what can we change about it? It's the natural instinct of the car enthusiast. What's the first stock part you replace?

We're fairly conventional in that, unless the car was previously owned by someone like-minded, new tires are at the top of a very long list. Few new cars come with the kind of rubber we want or need and used cars generally have some tire wear, thereby allowing us to justify spending more money on a car we just purchased. It's also one of the easiest, quickest performance swaps you can make and yields immediate results. And, you know, if you're going to be replacing the tires anyway why not some new wheels? And if you're already going to be down there might as well save on shipping and get some adjustable coil-overs, cat-back exhaust...

Okay, it's easy to get carried away, but the question is what's the first stock part you replace.
