The Infiniti G35 and Nissan 350Z, sharing much of the same design, are great handling sports cars just the way they came. However, there's always room to improve, and lots of aftermarket parts companies have worked to make that happen.
Coilovers improve your stock suspension by replacing the OEM strut and spring, while also giving you more adjustability. They let you lower your car, not only for the aesthetic, but for improving handling with a lower center of gravity and decreasing body roll. While lowering springs are another option, coilovers will give you much more control over the way your car handles.
