The STI Front Under Spoiler enhances the vehicle aerodynamics of the Liberty, while making the vehicle look lower and giving it a fast, GT style appearance. In wind tunnel testing the front spoiler improved the front lift coefficient (CLf) by approximately 80% (when tested with the STI Boot Spoiler). The optimum aerodynamic balance is achieved when the STI Front Lip Spoiler is combined with the STI Boot Spoiler. High speed handling of the vehicle is therefore improved. As a finishing touch, the spoiler incorporates a distinctive STI emblem
