I was going to do much more to this, but it's been hanging around too long now and new plans are getting too tempting, you know how it is 
I've included the open version as there are more layouts to be had. I had a few plans for more after I'd built Route 3, but unfortunately I was doing it on paper and forgot about the bumps
Because of this, some of the corners that I haven't used just don't work in practice, but enough do that there's room for variation from these three routes.
Routes 1, 2 and 3 have been extensively tested and tweaked and are suitable for all cars, although there is one bump that the MRT really, really doesn't like.
That's Street racing 
There are pits and a separate 'admin lane' where the start points are situated.
Route 3 is currently running on 'PiranMOTO Test Track 6', although that is dependent on my not-so-reliable computer being up and running at the time. There's a fair few times in the !top table for comparison.
