Note
the unusually large slot between the flap and main wing element.
Typically this slot is around 1 to 2% the main plane chord dimension and
in this case it definitely appeared larger.
The wing mount attached to a composite structural beam that was bonded to the underside of the bodywork. In testing, the 2KQ had a structural failure of that load bearing composite beam. In response to that, Reynard modified the load carrying beams with aluminum reinforcing scabs.
Notice the ducktail extension on the rear bodywork (black carbon bit). The tail extension reduced drag while also increasing rear downforce.
Looking
underneath, towards the rear of the car. Note the two structures
pointed towards the camera. These are the load bearing beams for
the wing mount. They are bonded directly to the body work and poke
out through the top.
