In a separate Mailbag post, we responded to a question about choosing a nitrous oxide system. Although nitrous oxide is a rather simple concept, tuning your engine to take advantage of the extra power potential can be a little involved, especially when you get into the high-horsepower or multiple-jet nitrous kits. Fortunately, the gurus at NOS have
In this Summit Racing Quick Flicks video, you will learn the basic differences between shocks and struts. Struts are similar to shocks in that they dampen road vibrations; however, they are a structural part of your vehicle’s suspension.
