One of the very few components of this build that has not had to be custom made is the ultralight flywheel. This flywheel, manufactured by TTV Racing, weighs a teeny, tiny 3.2Kg and is designed to take a common 7.25" (184mm) twin plate race clutch. The clutch I have is from AP Racing and has twin 4-paddle cerametallic clutch plates. Compared to a standard type clutch, this setup is massivley lighter, coming in at just 3.7Kg but the light wieght isn't the main benefit, bringing that weight closer in to the centre, thus reducing the moment of inertia, allows the engine to rev more freely!
