Supercheap stock most of the urothane bushes for holden and falcons. They will order them in for you, it still is cheaper than the other places as i found out most of the manufacturers get it made from the same place in QLD. they actually get nolathane brand. I rem the guy are All springs' told me there are only really 2 brands and alot of places only stock them. Also i know Whiteline sells them also but are slightly dearer.

I replaced my whole car (previous ride) and i tell you it was the best investment as it stopped all the shakes and improved handling. You don't get new bushes with shocks.
It is slightly rougher but i don't think you will notice it much.
