This conversion is definitely on my list. Kerim, essentially the parts you mentioned are what's required to convert the brakes, but I think to remove the individual components it is more work than just swapping the entire trailing arm assembly out. And what use would a wrecker have for a bare trailing arm?

If you want to find out more about the conversion take a look at the following links:

http://www.hazone.com/hdiscswap.htm (quite a detailed guide based on the hybrid Civic using the US Civic Si as a donor, not sure what the equivalent model in Oz is)
http://www.geocities.com/_nitro_/rea...reardiscs.html (another detailed guide again based on the US Civic Si as donor)

I think this is a really good modification for looks, performance, and safety.
