Has anybody had a problem with 20mm hubcentric rear spacers? I fitted mine yesterday and immediately i knew there was a problem when they made a knocking noise. It seems to do it mostly when setting off upt to 20mph and when braking at low speeds, Ive got 17's and coilovers but they arent really low, ive also taken the wheel off to have a look and i cant see and catching anywhere. Im going to take them off tomorrow incase its doing some damage
