At the moment I am running 1/32 cars on my 1/43 track, with some success.  I don't suppose this would work with those wide, GT and Le Mans cars but for my Minis and E-Types, it works fine, though strategically placed fencing helps keep the wider cars on track.  I haven't tuned any of my cars but they can all go incredibly fast on this set up and even with fencing and magnatraction, can fly off, into the fencing, at corners.  So there is still plenty of challenge, improving lap times.
I am pleased with my self designed layout, which makes the most of my limited space.  I hope to be getting some scenery over the next few weeks and hopefully get my Policar 1/32 track, up and running after Christmas.
