Im known for asking silly questions so here go's

Just started TT conversion project and find I have a physical problem retaining the gearbox, (gearbox centre to driveshaft clearance for motor)

If I can lock up the haldex to give 100% drive

I know the first problem is possibly not having the optimum drive ratio, that's why most conversions retain the gearbox.
Now this is where I need help, to overcome this problem is it possible to control a DC motor similar to star/delta control on AC industrial motors, so you have, effectively two modes low speed and high speed, maybe series and parallel?

Come on people we are talking EV we shouldn't need the gearbox

I originally planned using gearbox to motor set up and removing all the rear drive parts to reduce weight/friction etc but I would achieve the same by not using gearbox and front drive shafts.
My other option is to source the 2 wheel drive gearbox option for this car which has different clearances due to not having the rear drive interface.
Measure twice cut once.
