banging suspension

[DUNNY]

can any one help i've got a mk3 20ltr 8v and its been lowererd i have 15" rims but when i go over a bump sometimes theres a loud bang-knock coming from the back shocker i've been told its where the car has been lowererd but i've seen plenty as low it been dropped about 20mm lower than standard i have changed the springs but no better the man at garage said its bottoming out on the bump stops but i cant see that would make a bang-knocking noise and sometimes i can feel it through the floor its really starting to pi** me off hope you guys can help

are the rubber bump stops missing?

they are still there apparently theyve been cut down dont know why

It will be the rear bushes that are worn out. I believe this is a common problem. Also check the front bushes as these will be more than likely on their way out also. hope this helps.

is it the axle bushes???
