T420 chassis is made and developed for the centrally positioned layshaft. The framework is completely redesigned to work with the narrower mounting bulkheads and permits to mount both much longer suspension system arms in addition to optional brief arms. The aluminum solid chassis gives better control, stability and makes the vehicle easier to drive in high traction carpet conditions. Extensively tested and recommended for high- and very-high traction songs, this slim framework is CNC-machined from 2mm premium Swiss 7075 T6 and also black coated.
