Cannot imagine much demand for gear unit, nice for street for the serious customers but 99.9% of street customers happy with stock limited slip. Those in competition usually want clutch pack setup like our OS GIKEN. We have the OSGIKEN limited added to our Race ND when we were running AVO turbo at 12PSI and 300 ft/lbs torque at the wheels....and it works perfect.
We sold the Quaife ATB Differential -QDF9F (gear unit) for NC for years, now they are not really in the USA anymore so I don't expect them to do ND setup and make it easily available here. IF you really want that, you might check with their overseas office to see if they have done ND version.
