Give your vehicle the perfect stance and get your tires more flush with the fender. Wheel spacers increase the offset or the distance between the wheel and the wheel hub assembly. Spacers are also often being a necessity when upgrading to big brake kits allowing the calipers for more room in order not to touch the wheel. Many aftermarket wheels also come only standard sizes, by adding wheel spacers you achieve the offset you desire and not what the Manufacturer thought would look pleasing. Spacers and adapters are available in many different sizes.
