Rear trailing arm bushes.........they sit towards the front of the rear wheelarch area and fit inside the trailing arms.
The one in pieces is the left rear one iirc and the one slightly mis shaped is the right rear one......
On my rally style jump I guess the already rusty parts just gave out on the right rear when I landed heavily. Hence the very nervous feel of the car since that incident.
When cash permits I will replace the dampers and springs as well to freshen the car up a bit more, probably with some coil overs.
Karen did warn me numerous times to slow down during my stay but I can't help but enjoy driving the car so fast
I have learnt my lesson now though and will be cruising about when I take the ZS out in future.
