On both my previous M3's & EVO X I ran a ducted setup. On the tighter tracks I had the NACA Ducts fully open.

On a fast track like LRP I had the ducts completely closed.

Depending on your braking skills, type of track and pad compounds, you may need keep an eye on pedal feel, then play around with how much the ducts should be covered, etc.

For me the ducting was to extend the life of my front pads. Which it did by about 25-35%. The pads I was using at the time had a narrower heat range to work...
