There is a lot of mixed information when it comes to the safety of wheel spacers. But at the end of the day, it really depends on the quality of the spacer and if it is installed correctly. Below we have listed exactly what they do, the different types that are used, as well as a detailed fitment guide for both lug and hub centric options.
Wheel spacers are devices that fit onto the studs of the axle or hub, behind the wheel on the vehicle to create an additional clearance between the wheel and hub assembly. These spacers tend to be most beneficial to certain custom wheels. This is due to the custom wheels sitting too close to the existing inner wheel well.
Bolt-on wheel spacers are usually typical with enthusiasts wanting to widen the stance of their vehicle or to fix backspacing issues. Also, with bolt-on spacers, the original factory studs are used but the lug nuts are provided with the kit.
These are available in a hub-centric and lug-centric option. Hub Centric centers on the hub of the vehicle at the same time simulating the piloting lip on the face side leaving the Lug Centric option only being centered only by the lug nuts.

Slip-on wheel spacers slide over the existing studs will be hub-centric. This means they will pilot the center of the hub and will have a lip to pilot the wheels. Longer wheel studs may be required with these spacers.
You must ensure that at least 6 threads are fully engaged in the lug nut after the installation of these spacers. Check out more of our slip-on options for Mustangs to get the exact fitment and spacing that you need!
