Time to kill in Sydney after summernats, what to do?

[*rayman*]

We are heading to the summernats in january... and we have a few days in sydney afterwards, what should we do while we are there? It's a No chicks holiday, so car stuff is what we are looking for.

Anyone know of places we can get early falcon parts, and mustang/camaro places in sydney? And anywhere in particular we should go for a good feed?

Are rocket industries open to the public, they are in sydney somewhere arent they?
