Carrera digital 132 on a 4x8 layout

Hello all. I am brand new here and brand new to slot cars. Before I purchase my first set, I'm looking for some guidance.
I've found a really nice deal on a Carrera digital 132 Streamline set (http://www.amazon.com/Carrera-32-Digita ... B004OBY87M). By the way, I'm not buying it through Amazon. I've found a much better deal from a LHS, but there is the link for reference.
Also, I have a Mac, so I can't use any of the track layout software that I've seen.
My issue is that I want to set up a 4x8 layout until I can arrange for a larger space to make a bigger layout. But through my research, I've discovered that the Carrera tracks are much larger than the other 1:32 tracks. All the searches I've done bring back 4x8 layout results with Scaletrix and other brands, but I'm having a harder time finding Carrera layouts examples at that size. So can I set up a decent layout with a pit lane on a 4x8? A 5x9 would be the absolute maximum that I can go in size at the moment, but I'd really like to stick with 4x8 if at all possible.
Any guidance and/or suggestions would be greatly appreciated!
