This wing made a significant change to my 996 because the popup spoiler was not big enough. The moment i put a front spoiler I changed the aerodynamics and you could feel the lift at high speeds (scary). The wing is not an Aero Kit, but technically it is a Tequipment wing which is as close to Porsche as you can get. It had a lot of blemishes but I have a local body work group that loves to work on Porsches.
