The latest generation front-motor front-wheel drive FF series chassis is the FF-04 EVO Chassis kit, which builds on the carbon fiber double-deck concept of the FF-03 EVO Chassis and takes it to a new level with a range of upgraded and newly-designed parts. The chassis offers superior cornering, and employs a double deck layout with 2.5mm thick lower and 2.0mm thick upper carbon fiber decks. Suspension arms use the same design as those on the TRF418 touring car chassis, and power is transmitted via an oil-filled gear differential unit housed in the XV-01 chassis design gearbox. The result is reduced track surface contact during cornering, and even sharper handling.
