The TMT-200 is an advanced transaxle transmission solution designed specifically to suit the latest generation of mid-torque single-seater and GT racing applications. The TMT-200 project marks the next step-up in torque capacity from the hugely successful FTR-200 gearbox, and provides a far lighter, more advanced replacement for the NMT-200 unit.
The TMT-200 is an advanced transaxle transmission solution designed specifically to suit the latest generation of mid-torque single-seater and GT racing applications.
The TMT-200 project marks the next step-up in torque capacity from the hugely successful FTR-200 gearbox, and provides a far lighter, more advanced replacement for the NMT-200 unit. Optional integrated semi-auto actuators further help to reduce overall vehicle weight while providing improved design flexibility thanks to notable space-saving benefits.
Specification also includes a TPT Powerflow™ limited slip differential, internal oil pump, integral rocker post mounts plus suspension and crash attenuator mounting points.
With an increasing demand for relatively small capacity, turbo charged powerplants coupled to lightweight race vehicles, the TMT-200 addresses the balance between weight, technology and torque capacity to provide the minimum possible compromise in class.
