The wheels on a C5 (2001 - 2003) are centreless and require an adapter plate to fit the wheels to and then on the shaft of the wheel balancer. You have to go to a good quality tyre shop and the person really must know what he is doing. The balancer has a tolerance of 5.0 grm, this is no good for the C5 as its got to be 0.00grm. I can assure you that this will stop the vibration if you have all four wheels balanced, I had mine done three times and thought there was a fault on the car, using high quality equipment to balance all four wheels cured it. Good luck
