If I were racing one of these in WEC or IMSA, this is exactly the kind of full race aero absurdity I would want to bring to the table. There's a reason why the Emira GT4 has a similar (though far more sculpted) wing.

This is one of the few cars in a production body shape that already incorporates very intentional aero into the design, and if it could be increased to the levels appropriate for serious motorsport work we could see the Emira do some really interesting things in international competition.
