Sorry to keep asking silly questions. got 60mm springs on the fron ans as far as i can identify is that maybe the strut cup is dropping over big bumps then banging when the spring hits it? Any ideas?

Have you still got bump stops fitted to the struts? Mine did this as the last ones had disintegrated.

I cant remember if it has :/ i'll have a check tonight. The only thing i can put it down would be dampers not stiff enough and maybe its the strut cup re contacting the spring (as they are 60mm lowering springs)

Could the dampers be too long and hitting their endstop?
