Factory wheel stance is narrow, and can feel unstable during high speed driving and cornering. With wheel spacers, you can bring out the wheels and give the vehicle a wider stance. Wider stance means the car is more stable and may reduce body-roll when driving or during cornering. The universal hub design allows you to put on other wheels that might have different hub size than your oem spec. These spacers have build-in wheels stubs and the specially taper designed lock nuts are included to ensure the spacers are properly secured and in position. The installation is easy, just remove the wheels, bolt on the spacers, and put the wheels back on.
