Rear wing as air brake design - validation model model

[Aerokin]

Hi guys,
i am buiding a rear wing for a sports car that can be used as air brake just like in Veyron and P1. I have selected several aerofoil profiles and tested them using XFOIL. I am designing a linear actuator for the rear brake.I need a reference model like the rear wing of the veyron or any other existing car ( existing car that uses an active aero airbrake) so that my results could be compared with the car to validate my research to produce comparable aerodynamic characteristics. Does anybody know any rear wing design or aerofoils used in any existing sports cars? Please do help..
