Most modern aftermarket rims are made with an oversize center bore and the centering ring brings that bore size down to the 4th Generation MX5 hub fitment of 54.1 mm. These help properly fit your new alloys and are made in metal for our 6UL wheels! Price is for set of FOUR rings, so you only need ONE order of these...please do NOT order FOUR SETS unless you really want four sets!!!
