Oh Dear Uther, the old sagging springs saga once again. What a story this has been in Australia and around the world for that matter. I have the same year and model and suffered the same problems as did many others. Go through the extensive posts on this site on the issue as a start (BTW,the lowering blocks are standard on our model cars)
Sounds like you will be up for new springs. I am happy to provide detail of my experience if you require but read the DaveW post on spring replacement first up.
