PART NUMBER: 21-1060PF
Picture shows just one ring but this is a SET OF 4 rings.
Most modern aftermarket rims are made with an oversize center bore and the centering ring brings that bore size down to the Miata/Fiat 124 54mm size. These help to properly fit your new alloys.
Price is for set of FOUR ALUMINUM rings with retaining clips for Enkei wheels.
Brian's Tips: Grab your Anti-Seize and use a smear all sides of the METAL ring or it will seize eventually on track cars to the wheel or the hub.
