Right, getting the hump with this now. Love my A4 to bits but something is bugging th eHell out of me. When driving down th elanes and hitting a bump mid corner I get a knock and feel like something is loose. The arms are new and the ARB rubbers are new. Only bit left is the top mounts. Are these prone to going? Car has 120k on the clocks now and I can be a bit of a hooligan with the old girl. How much are top mounts for these? Main Stealer items or ECP?
