I see you found the Aussie forum
Welcome aboard
Plenty of helpful people in here, who will be more then happy to assist with technical questions and stuff
The classified section is a great place to pick up cheap pre-loved and the occasional new part
If you are planning on modding your car check it out first or post a WTB (want to buy) and someone might have what you are looking for
Looking forward to seeing how your build takes shape mate.... and once again welcome aboard
