The higher the wing is on the car, the cleaner the air it sees.  A wing in clean air will produce the same downforce at less of an angle allowing you to run less wing and less drag for the same amount of downforce, or create more downforce than possible with a shorter upright.

Made to work with the 996 Cup wing.

Laserjet cut from aircraft grade aluminum, professionally powdercoated for long life and durability.
