Project 4X double vertical topdeck and top-deck stiffeners
The new Topdeck is the base for all the new flex options. It consists of two equal shaped vertical oriented 2.5mm carbon fibre plates. The plates are connected to the front and rear suspension with a machined aluminium adaptor plate. Unlike flat topdecks, the vertical oriented double topdeck still allows a lot of linear torsional flex, but basically eliminates any longitudinal tweaking and reduces torsional tweak drastically. It can be run in addition to the kit aluminium center stiffener. The H-shaped stiffener plate can be removed when the topdeck is used to create more flex in the front and rear section of the car.
Project 4X topdeck stiffeners
To stiffen up the assembly further, there are two topdeck stiffeners available which connect the vertical double topdeck to the center stiffener/motormount assembly. Both can be used individually, to tune front and rear flex individually.
With these optionals the 4X can be adapted to any track condition from high to low bite, carpet, asphalt, hot and cold temperature. Also with the topdeck the Project 4X car is almost immune to tweak due to crashes.
Viktor Wilck used these new parts in the recent Reedy race and was fighting for the overall win wih the Project 4X to finish a superb 3rd overal.
