I realised it was the coilover.

The damper rod itself. it turned out both sides were bent.

my struts use a sleeve with female thread to mount the coilover to the spindle, which allows for separate ride height adjustment.


I did some researching and unfortunately these zeal coilovers use a 51mm thread on the body, and most other use a different thread. this makes replacing the coilovers pretty tricky without re engineering the struts.

For now I have straightened them as best as I can and have put the softer springs on. The car seems to ride much better although I haven't been able to properly drive it. I think the damper rods are likely to bend again now, so I need to find replacements.
