Importing a Cosworth to Perth

[skinkis]

Hi!
I recently moved to Perth from Sweden.
Back home, I´ve got a -86 RS Cosworth. I was planning to bring it over in a couple of months, but before I do that I figured I might as well ask you guys for tips etc.

I´ve seen left hand drive cars here before, so I´m guessing that it shouldn´t be a problem, but the car is "lightly" modified... Will this cause any problems when I take it to the pits for a registration?

Has anyone here imported a car and knows what type of documents I might need?

I´m posting some photos of the mods as well...

Thanks!
