GReddy Aero Kit ROADSTER (NCEC) Side Skirt Front Spoilers are the first point to receive airflow resistance; the design of the front spoiler determines the final handling of the vehicle. The GRACER front spoilers are designed to reduce airflow going beneath the vehicle and also direct air to critical areas such as the radiator and intercooler. While driving air turbulence occurs around the front tire, this turbulence can disturb airflow all the way to the back of the vehicle, where it can reduce the function of the rear spoiler. The GRACER Side Skirt is designed to smooth out the air turbulence towards the back of the vehicle, to achieve safe handling of the vehicle.
