I personally drive an SRT roadster and don't need the effect of a "spoiler", but I just would re-think the notion of sticking on a plastic body part across the back of my classic car just because it might make my car stand-out. If you think about it, you'd only make it "different" in the eyes of another xFire owner! The average person wouldn't notice anything. Just my $.02
With that said ..... I agree that you are one of the few to think about and try to market new items of our xFires and I encourage you to keep up the work.
Seeing as this is a duck-tail design, I don't believe it would add much downforce. The SRT design is a true wing and adds a very noticeable push down on the hind-quarters.
This new add-on WOULD, however, assist the normal spoiler in disrupting the airflow, especially as speeds climb. Aesthetically, I think it would help immensely as it would add a bit more visual weight to the rear of the car when the spoiler is retracted.
If I still had the small spoiler, I'd be all over it.
