Coming from Yokomo and made for their YD-2 and YD-4 drift cars to further enhance the performance of the cars is the front and undertray diffusor kit that consists of a front and undertray diffusor that will help to achieve improved front end grip using the front aerodynamic help while the undertray diffusor accelerates and guides the air towards the rear end of the chassis for improved overall grip without loosing the ability to precisely drifting the car. The front and undertray diffusor are usable for both the YD-2 and YD-4 kits. All parts are moulded from impact-resistant composite material for durability and a low weight.
