Use these to fit wheels with larger hub bores on to your Subaru. They're plastic, so you don't have to worry about them seizing on to the hub or wheel like metal rings can.
Outer diameter is 73.1mm, which is the most common aftermarket wheel centerbore size. (Check your wheel specifications if you are not sure.) Inner diameter is 56.1mm to match all Subaru hub bores.
Note that we don't recommend using these on track, since the plastic rings can melt from the high heat generated from sustained braking. For cars that will be seeing track use, we recommend .
Sold as a set of four rings.
