I put some pics up here recently:

Apart from the steering wheel (Doncaster BMW) and exhaust (Remus Australia), all the bits and pieces have come from overseas and all the vendors and products are easily found here on M3Post. Just shop around for shipping prices and make sure things are not sent as pure freight as there are lots of handling charges...My diffuser cost around $500 in freight processing fees just to get from the tarmac to the DBShenker warehouse!
As for getting the bits installed, I am lucky that my partner has worked in the prestige service industry for awhile so she knows some good people. I have used Donnellans in Box Hill for tyres/wheels (Mark there has an E93 M3), B&M Refinishers in Fairfield are currently painting and fitting the boot and Steve's Wheels in Brunswick will be doing the suspension work.
