Rear wing for Norev Peugeot 908 HDi FAP

Rear wings often break on 3 inches diecast cars, so I designed one for the Norev Peugeot 908 HDi FAP, but I assume it could be used for other sports prototype cars.

The base is made of two 1 mm squares, separated from each other by 2 mm. Everything else is 1 mm thin and well aligned for printing reasons. The two "legs" are too long, but better too long than too short to install them.
The angle between the base and the wing is 10°.
The wing itself is perfectly flat, but I'm working on a tilt
