Hello everyone, If you have aftermarket rims, hubcentric rings are a must if you take your car above 60 MPH. There seems to be confusion out there as to whether these rings do anything. My rim supplier even told me not to use them, as the rims are lug centric. Im telling you now that they absolutely make a difference. I had high speed vibration that I have been chasing, and put these rings on as a last resort. The vibration is gone! I can even feel the car is more “solid” at low speeds. If you have aftermarket rims and a slight annoying vibration while driving at highway speed or above, do yourself a favour and order a set of rings. You wont be disappointed. Best $30 I ever spent.
