Most wheels made to fit Subaru’s have a “high offset” (+48 to +53) adding these wheel spacers will effectively lower the wheel offset by how thick of a wheel spacer is used (25mm or 30mm), what this means is the wheel will be pushed outwards bringing it closer to the fender and giving the vehicle a more aggressive stance. Wheel spacers also will often give you more room for bigger tires on cars with struts by moving the tire out from under the lower spring perch. They can also allow you to run wheels that without wheel spacers won’t clear your brakes. These wheel spacers are extremely high quality, we use them on all of our big builds.
