Found something a bit more than a "leading edge slot".

I'd call it a true roof wing, and not a spoiler.

Proton R3 Satria Neo – short test drive impressions

A different car and wing/spoiler, same color?

Did you tape the gaps between the kammback and the car--and any other gaps in the kammback construction--to avoid a possible parachute effect?

I did seal all the unnecessary gaps when I built my Kamm and it provided a loss of about 4%, as it was built... I meant to revise and retest it but never did, focusing on measuring the gain from lowering the car...
