These components are aftermarket additions designed to increase the offset of a wheel in relation to the vehicle’s hub. For example, installing a set will effectively push the wheels further outward from the vehicle’s chassis.
The utilization of such parts can enhance a vehicle’s aesthetics by providing a wider, more aggressive stance. Furthermore, they can improve handling characteristics in certain situations by increasing the vehicle’s track width. Historically, these have been employed for both visual modification and performance enhancement across various vehicle platforms.
