T420 framework is made and developed for the centrally positioned layshaft. The framework is wholly redesigned to support the middle drivetrain system and narrow mounts the long supply suspension. The updated design moves the primary bulkheads towards the guts by 1mm, and includes mounting holes for the long arm and brief arm suspension holders allowing switching between the two designs utilising the exact same framework. The 2.2mm thick chassis is CNC-machined from premium-grade graphite product. This framework is developed for all asphalt surface conditions. The slim chassis is just 86mm wide with a variety of chassis flex alterations that help produce excellent traction and provide excellent steering traits.
