The Baer wheel spacer is a great tool to get a desired brake system to fit inside a wheel. The Baer wheel spacer's are fully machined in house from US sourced 6061-T6 aluminum to ensure they are flat and true to form. They are available in a wide variety of bolt patterns and sizes to ensure the perfect fitment for your application!, , Make sure you have enough thread engagement on your studs before adding spacers. In many cases most cars can not take more than 1/4" (.250) with stock studs (and this is not always the case). Please make sure you have the proper length studs to add wheel spacers., , Make sure your car can accept the amount of spacer you are looking to add! Pay attention to fender clearance, and tire rubbing!
