i have a 2008 sri
i have just fiitted sachs supertrouring shocks all around the car.
i have eibach 30mm springs on them.
im getting a knocking/rumbling from both sides at the front end when going over rough roads/potholes etc.
when i removed the wheels, i could lift the struts up and down with out issues - as if the shocks were knackered.
i have fitted new drop links as well.
the bottom arms/bushes/arb/ball joints etc look a if they dont have wear/play on them.
all the bolts etc are all tight.
could it be possible that the springs are no good for the shocks?
i was actually considering refitting the original springs to see if it would help, but ive chucked the originals out.
any help please coz im at my wits end with the noise/knocking
just noticed ive selected the subject as vxr - it should be vectra
