How about a name that reflects the look of the chassis.
To me it looks a bit like a delta wing fighter, a capital A or a dart with those swept back bits.
So, BMI Delta would be good, you'd be paying tribute to an early pioneer of 12th racing. If you don't like that, then BMI Dart also works. Both are short and punchy and sound fast.
There's the ability with the dart to do some word play, like: "Be at the pointy end with a Dart!" "With a Dart you're on target for success."
