In the world of top-end performance, every decision made about a specific car matters.

In the world of top-end performance, every decision made about a specific car matters. Particularly if the car is built for the purpose of racing, incremental adjustments that provide a performance edge can mean the difference between victory and defeat. That’s why supercars have ridiculously high price tags and the ones that are actually used for racing never drive a foot that they don’t have to.

Modifications and tuning practices might aim at ensuring that the engine breathes better and revs freely to higher RPMs

But most of us don’t drive high-end racing cars. As much fun as it can be as enthusiasts to get the most performance out of our own vehicles(especially if that means we can fool around with them in the shop or treat ourselves with upgraded parts), how does performance come into play when we’re simply heading over to the grocery store or driving home for the holidays? The answer: quite a bit. Even if you don’t care at all about getting your car to accelerate quickly or reach a high top speed, performance still impacts just about every aspect of your driving experience.
