I bought a B5 a year or so back and was unlucky to pothole wheels on two occasions. I bought a set of refurbished rims on eBay and had new tyres fitted but now get a vibration throughout the car which I am told that the rims have flat spots and a slight buckle. Upshot is I need new wheels. Audi say they will not make a goodwill discount and new audi wheels (offset ET20) are over £3k for a set of four. I would welcome any ideas of how to source cheaper or perhaps a 3rd party aftermarket supplier who can supply with this ET20 offset. Many thanks in advance if anyone can contribute?
