Based on the World Champion IF15, this wide chassis kit features exclusive new front and rear shock towers and body mounts as standard items, as well as wide tires to create a 235mm wide race chassis for use with racing-type body. The newly designed front one way drive is included in the kit to help produce sharp turn in that matches the racing-type body. The racing-type body boasts unparalleled aerodynamic performance providing higher cornering speeds than that of a regular sedan body. Most of the existing optional parts for the IF15 can still be used allowing you to upgrade your car and improve performance.
