599XX winglets
Ferrari said that the C-Pillar winglets directed air down the backlight,then up,over the rear spoiler.It cost them around $200,000 in wind tunnel time just to dial the shape,size,and placement in.
The 1975 Ferrari Cr 25,at Cd 0.256 comes in below the Cd 0.285 599XX,without any of the gee-whiz excrescences.
