Once we have finished with the UN1 (i.e. we are past the testing and prototype stage), we will need a repeatable solution for the transaxle. For racing with our current available tourque (450Nm) a 2 speed box is probably needed, but if we can extract a bit more torque or RPM from the motor, we may get away with 1 speed which would be better.
Options if we build from scratch:
Or if we have enough torque, just use a R200 diff... e.g. http://www.trademe.co.nz/Browse/Listing.aspx?id=337001489
