I re-read the rule book and think we have a place to run all the cup cars.... Streamliner....
Since they are not based on any production vehicle, and don 't use any production parts, they fit Special Construction, and since the wheels are faired, Streaminer...
Bring 'em out boys, you can race them if they meet the other safety requirements...
(disclaimer... I don't represent the scta, their opinion may vary)
