Hey Damian,
Firstly, Welcome mate! Might be worth sticking a post in the Intro thread too

Good to see a few more Gen 3's appearing. It'll make a few more members on here happy.
As for your suspension, check the For Sale thread as there is often people selling C/O's and / or similar.
As for opinions, I'm running Tein C/O's and find that it is a good compromise for adjustability, firmness and comfort compared to the Billies that were in the car. If you want them for looks more than anything else, then there are cheaper options out there. In Melbourne, maybe touch base with TuSpeed in Coburg.
Good luck!

Cheers
