Man, over 40 views and no comments.

Here I thought I was doing something useful, too...

I remembered Trebuchet's CFD thread from a while back and decided to compare my results. I'd say he was doing some pretty good modeling!

I drew a line of my estimated flow separation point on this shot:

Vs:

I'm also now more encouraged to do my decklid extension, since he got these results with one modeled:

If the VGs are drawing more flow down the rear glass and onto the decklid, further airflow smoothing via an extension should help minimize the total wake, too, no?

So what do you guys make of all this?
