siggy

Is it normal for a 2001 wrx to sound really noisy when doing about 90. even when i am on the motorway and go over the cats eyes it is extremely noisy and sends a vibration up through the facia. Also when cornering at speed or accelerating at speeed there is a vibration from the suspension. Is my suspension geometry out or is it something elase ????. The car has only done 18k. thanks in anticipation.
