Rite guys and girls I've replaced my supsension with a koni sport kit about year ago. I now have one side being lower than the other side. Drivers rear being a lot lower than the passenger rear . I've heard it's common for the springs to wear.

It's even worse now I have escort cosworth wheels .

I've changed the springs and shocks .
Checked the anti roll bar and bushes

Found one bush on the hub spilt into too but going to replace them

Thanks in advance ...... James
