Wheel alignment is absolutely crucial when modifying your car. Alignment can effect every aspect of your driving experience, from straight line stability, under steer, over steer, acceleration, braking and tire wear. Although stock components allow slight alignments from the stock suspension settings, they often are not able to properly align the car after the suspension has been modified. From the factory, most cars are set to have under steer and for optimum tire wear at stock height; under steer is often undesired from a performance standpoint but is always dependent on driver style, therefore the adjust ability of the alignment of a vehicle is critical when tuning for speed. The clock does not lie and having the vehicle alignment can make seconds of a difference.
