Based on the parameters you've given, the boundary layer separation should cause a stall (zero downforce) condition at around 10 degrees declination. This boundary layer separation can be reduce by inducing vortices before the air reaches the spoiler.
In any case, I'm interested to hear what ended up coming out of this, and what declination you ended up using.
This is the first question I've had regarding the "wing" And if you want the detailed answer, it will take awhile and I probably won't finish it in one post... If you want the short answer, it depends on the track... I have found the range from 11 to 9.5 degrees... I learned that 11 degrees is too much at speeds over 125 mph because it creates too much drag and downforce on the rear and seems to lifts the front end... Here's a perfect example, where you can see the front end lifting and the rear end plastered to the pavement... This was with 11 degrees and speed somewhere around 125...
So let me start by saying it wouldn't be on the car if it was a daily driver because it looks like some pimped-out ricer IMHO... But, it started as an experiment to see if I could keep the rear-end stuck to the ground enough to prevent the traction control from kicking-in during high speed corners...(this was before the TC was disabled) I was taught to "power slide" thru corners and keep the car just on the edge of spinning by throttle control, but the invasive ESP on the Crossfire would just cut the throttle and apply braking pressure the minute it sensed rear wheel slip...
I'll have to finish this later....
