Further contributing to the weight advantage was the adoption of lightweight sequential manual transmission originally developed for Lotus 12 by Richard Ansdale and Harry Mundy incorporating the unique sequential-shifting motorcycle gearbox, and a ZF limited-slip differential in a common Magnesium alloy housing to form a transaxle, which also provided the mounting points for inboard rear brakes.
