A standard push fit expanding plastic rivet which is used to attach the plastic wheel arch liners onto several different Subaru vehicles. The clips are used on some models of the BRZ, Impreza, Forester, Legacy and Tribeca.
The plastic trim clips fit into an 8mm hole and are identical in quality and specification to the OE parts.
Please check the details carefully before you order. Every vehicle has many different clips and fasteners. Even if the ebay compatibility check says these are used on your vehicle, that does not mean that they are the only clip and will be the ones that you need. It is important to check the photo, part number and dimensions before you order.
