The S120 chassis consists of 2 main elements, the 2.5mm thick carbon fibre chassis plate and the rear single piece aluminium motor pod. The chassis uses a T-bar system, which has adjustable tension thanks to its unique tweaking system is damped using a conventional centrally mounted shock absorber together with a laterally mounted floating monoshock. The front end of the car is completely adjustable and utilises the now standard fixed lower suspension arms combined with active top wishbones, which together with kingpin mounted springs ensure that the car is able to corner at high speeds and soak up any small bumps found on the racing surface.
