Hey mate, they look like the Z-tune side skirts and rear pods.
I just bought a set of the skirts and pods from Bodyform Aero in NSW for $580 ($330 sides/$250 rear)
From all accounts I'd heard, Bodyform were the way to go so I took the plunge and gave them a try.
Peter and Allan there were very helpful and quick to respond to emails.
I've written more on here about my experience with them.

My car is currently in getting them put on, I'll be picking it up after work today so I can provide pics of what it looks like but I'm pretty confident it'll look good.
When I dropped the parts in to DT Panels, their reaction was "Whoa are these genuine? Are you sure?? They look very well made!" haha that brough a smile to my face.
