Designed based on extensive testing at Tsukuba Circuit, the ASM I.S. Design Front Aero Bumper IS-11 is the FRP version of the ASM I.S. Design Front Aero Bumper GT-10. It incorporates a larger front lip for additional front end downforce. The overall length of the bumper is increased by 30mm further enhance downforce. The integration of the lip reduces the need to additional attachment hardware for maximum weight savings. The radiator opening is also widened for additional cooling effect. The leading edge of the front lip is sharpened for additional airflow under the car and into the front opening. Design specifically to match the the wide Front Aero Fender -04, the bumper flow air smoothly over the front fenders for better aerodynamics.
