Rear Wing.

The rear wing is the most important aerodynamic device on the MINI John Cooper Works WRC. It produces significant downforce and sideforce at the rear of the car to help improve high speed stability. The shape of the rear wing has been modelled using Computational Fluid Dynamics (CFD) which simulates wind tunnel testing. Its design must meet strict FIA regulations. The wing on the WRC-spec car is the most significant difference with the S2000 car – it is much larger producing greater downforce and makes the biggest difference to the performance between the two cars. The rear wing is made from lightweight carbon fibre.
