Is this a rule that most people ignore then? As you can see from various rule books none of them mention the track width only the body.
Just pulled out a Speed 9 and it measured the same as the 8 and 12, 170 mm. All bodies flare at the bottom little after they come off the form, but you wouldn't want to use that as a measuring point.
Since the Speed 8, for instance, has probably been used at every 1/12th scale race at all levels for years it would probably be safe to say that any rules deviations it might have are being ignored.
So far today I've measured three Speed 8's, two Speed 12's and the Speed 9, and none of them were over 170 mm.
