hi as I am new to the modifying world, am just going by what I am told... I bought a mb6 and today a knocking noise has appeared. the noise it not there when I am giving her throttle or when I am braking, but when I let my foot off the throttle the knocking noise begins, I contacted the previous owner and he told me it could be the coilover, he told me the coilover are for an ek model and that's what it could be? I don't know and wonder if anyone else came across this problem or do they fit properly to start with? thanks philip
