I performed another wool tuft test to see if the airflow on top of the roof is flowing inline with the car.
This had to be done to ensure proper placement of the VGs at a 15° angle
As we can see, the airflow ontop of the roof is flowing straight, so I can install the VGs with a simple template.
First location will be 5cm upstream of the rear window, spaced 100 mm at 15°.
If that doesn't work, I'll place them 5cm downstream of the front edge of the hardtop.
