Feeling vibrations through your steering wheel after fitting new alloys? These little hub centric rings might just be the fix! They’re plastic spacers that sit between your car’s hub and the wheel, making sure everything is perfectly centered. This set converts a 73.1mm wheel bore down to a 66.1mm hub – so if your car’s hub is smaller than your wheel’s center hole, these fill the gap snugly. Result? Smoother ride, less vibration, and better handling. They’re heat-resistant, durable, and easy to install (just pop them in before mounting the wheel). You get four rings, one for each wheel. A must-have if you’ve upgraded your wheels or bought aftermarket alloys. Cheap insurance for your suspension and driving comfort!
