    Clunking sound from rear of car under hard acceleration in 1st gear

    Only happens under hard acceleration ( not dumping the clutch) say from 5mph roll - 1st gear, once power comes on it does a clunk clunk from the rear. I do have a sti turbo and other supporting mods so there is more power then stock. it also has a eibock wagon springs, so its slightly lower. I got under the car , but there inset anything noticeable. anyone have any ideas ? the only thing I can find on the internet is a clunk between gears , but that is not my issue.

    Could be your diff hitting the bottom of the car as power is applied to the driveshaft.
