Very nice write up so far. This will help many other applications where the vehicle weight and torque and tire size will be different from the suby applications. For instance the 914 midengine suby engine and tranny application that is popular. 2000 lb. midengine, 350 rwd hp 300ftlbs maybe with long street gears or close gears for the track, either with lsd.
Looks like the beginnings of a good sticky.
