Picked these up for some aftermarket wheels. The product claims to fit a 72.56 wheel diameter, but it was more like a 72.00. The spacer didn't fit the hub perfectly, maybe by a millimeter. As a result, the wheel was not flush with the plane of the wheel hub and rocked. Noticeable only at higher speeds but nearly gave my wife a heart attack when someone pointed it out to her on the freeway. I had to drive 45 minutes to get changed in the parking lot and remove the spacers. Imprecise milling. I probably should have checked if they are made in China before buying.
