The brand new Eliseparts sequential gearbox is a clean sheet design, developed from the outset for the Elise chassis, to be used with either the Honda or Toyota engines. Furthermore, it has been designed to work seamlessly with padleshift systems such as Geartronics. It has been tested in extreme conditions for well over a year now and is working perfectly, helping to achieve many race wins.
My particular gearbox is the 6 speed version with a 3.7 ratio final drive. My gearsets have additionaly been shot peened and REM coated for extra strength, longevity and quiet operation.
